GENERAL PRODUCT DESCRIPTION The ES29LV320 is a 32 megabit, 3.0 volt-only flash memory device, organized as 4M x 8 bits (Byte mode) or 2M x 16 bits (Word mode) which is configurable by BYTE#. Eight boot sectors and sixty three main sectors with uniform size are provided : 8Kbytes x 8 and 64Kbytes x 63. The device is manufactured with ESI’s proprietary, high performance and highly reliable 0.18um CMOS flash technology. The device can be programmed or erased in-system with standard 3.0 Volt Vcc supply ( 2.7V-3.6V) and can also be programmed in standard EPROM programmers. The device offers minimum endurance of 100,000 program/erase cycles and more than 10 years of data retention. The ES29LV320 offers access time as fast as 80ns or 90ns, allowing operation of high-speed microprocessors without wait states. Three separate control pins are provided to eliminate bus contention : chip enable (CE#), write enable (WE#) and output enable (OE#). All program and erase operation are automatically and internally performed and controlled by embedded program/erase algorithms built in the device. The device automatically generates and times the necessary high-voltage pulses to be applied to the cells, performs the verification, and counts the number of sequences. Some status bits (DQ7, DQ6 and DQ5) read by data# polling or toggling between consecutive read cycles provide to the users the internal status of program/erase operation: whether it is successfully done or still being progressed. Extra Security Sector of 256 bytes In the device, an extra security sector of 256 bytes is provided to customers. This extra sector can be used for various purposes such as storing ESN (Electronic Serial Number) or customer’s security codes. Once after the extra sector is written, it can be permanently locked by the device manufacturer( factory-locked) or a customer( customer-lockable). At the same time, a lock indicator bit (DQ7) is permanently set to a 1 if the part is factory- locked, or set to 0 if it is customer-lockable. Therefore, this lock indicator bit (DQ7) can be properly used to avoid that any customer-lockable part is used to replace a factory-locked part. The extra security sector is an extra memory space for customers when it is used as a customer-lockable version. So, it can be read and written like any other sectors. But it should be noted that the number of E/W(Erase and Write) cycles is limited to 300 times (maximum) only in the Security Sector. Special services such as ESN and factory-lock are available to customers ( ESI’s Special-Code service ) The ES29LV320 is completely compatible with the JEDEC standard command set of single power supply Flash. Commands are written to the internal command register using standard write timings of microprocessor and data can be read out from the cell array in the device with the same way as used in other EPROM or flash devices.

DEVICE BUS OPERATIONS Several device operational modes are provided in the ES29LV320 device. Commands are used to initiate the device operations. They are latched and stored into internal registers with the address and data information needed to execute the device operation. The available device operational modes are listed in Table 1 with the required inputs, controls, and the resulting outputs. Each operational mode is described in further detail in the following subsections. on the device address inputs produce valid data on the device data outputs. The device stays at the read mode until another operation is activated by writing commands into the internal command register. Refer to the AC read cycle timing diagrams for further details ( Fig. 18 ). Word/Byte Mode Configuration ( BYTE# ) The device data output can be configured by BYTE# into one of two modes : word and byte modes. If the BYTE# pin is set at logic ‘1’, the device is configured in word mode, DQ0 - DQ15 are active and controlled by CE# and OE#. If the BYTE# pin is set at logic ‘0’, the device is configured in byte mode, and only data I/O pins DQ0 - DQ7 are active and controlled by CE# and OE#. The data I/O pins DQ8 - DQ14 are tristated, and the DQ15 pin is used as an input for the LSB (A-1) address. Read The internal state of the device is set for the read mode and the device is ready for reading array data upon device power-up, or after a hardware reset. To read the stored data from the cell array of the device, CE# and OE# pins should be driven to VIL while WE# pin remains at VIH. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. Word or byte mode of output data is determined by the BYTE# pin. No additional command is needed in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses Standby Mode When the device is not selected or activated in a system, it needs to stay at the standby mode, in which current consumption is greatly reduced with outputs in the high impedance state. ES29LV320D 6 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. The device enters the CMOS standby mode when CE# and RESET# pins are both held at Vcc+0.3V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within Vcc+0.3V, the device will be still in the standby mode, but the standby current will be greater than the CMOS standby current (0.2uA typically). When the device is in the standby mode, only standard access time (tCE) is required for read access, before it is ready for read data. And even if the device is deselected by CE# pin during erase or programming operation, the device draws active current until the operation is completely done. While the device stays in the standby mode, the output is placed in the high impedance state, independent of the OE# input. The device can enter the deep power-down mode where current consumption is greatly reduced down to less than 0.2uA typically by the following three ways: - CMOS standby ( CE#, RESET# = Vcc + 0.3V ) - During the device reset ( RESET# = Vss + 0.3V ) - In Autosleep Mode ( after tACC + 30ns ) set-up cycle and the last cycle with the program data and addresses. In this mode, two unlock cycles are saved ( or bypassed ). Sector Addresses The entire memory space of cell array is divided into a many of small sectors: 8kbytes x 8 boot sectors and 64Kbytes x 63 main sectors. In erase operation, a single sector, multiple sectors, or the entire device (chip erase) can be selected for erase. The address space that each sector occupies is shown in detail in the Table 3-4. Accelerated Program Mode The device offers accelerated program operations through the ACC function. This is one of two functions provided by the WP#/ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH (11.5~12.5V) on this pin, the device automatically enters the previously mentioned Unlock Bypass mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to reduce the time required for program operations. Only two-cycle program command sequences are required because the unlock bypass mode is automatically activated in this acceleration mode. The device returns to the normal operation when VHH is removed from the WP#/ACC pin. It should be noted that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. In addition, the WP#/ ACC pin must not be left floating or unconnected; inconsistent or undesired behavior of the device may result. Refer to the CMOS DC characteristics Table11 for further current specification. Autosleep Mode The device automatically enters a deep power-down mode called the autosleep mode when addresses remain stable for tACC+30ns. In this mode, current consumption is greatly reduced ( less than 0.2uA typical ), regardless of CE#, WE# and OE# control signals. Writing Commands To write a command or command sequences to initiate some operations such as program or erase, the system must drive WE# and CE# to VIL, and OE# to VIH. For program operations, the BYTE# pin determines whether the device accepts program data in bytes or words. Refer to “BYTE# timings for Write Operations” in the Fig. 21 for more information. Autoselect Mode Flash memories are intended for use in applications where the local CPU alters memory contents. In such applications, manufacturer and device identification (ID) codes must be accessible while the device resides in the target system ( the so called “in-system program”). On the other hand, signature codes have been typically accessed by raising A9 pin to a high voltage in PROM programmers. However, multiplexing high voltage onto address lines is not the generally desired system design practice. Therefore, in the ES29LV320 device an autoselect command is provided to allow the system to access the signature codes without any high voltage. The conventional A9 high-voltage method used in the PROM programers for signature codes are still supported in this device. 7 Rev. 2D Jan 5, 2006 Unlock Bypass Mode To reduce more the programming time, an unlockbypass mode is provided. Once the device enters this mode, only two write cycles are required to initiate the programming operation instead of four cycles in the normal program command sequences which are composed of two unlock cycles, program ES29LV320D E S II ES Excel Semiconductor inc. If the system writes the autoselect command sequence, the device enters the Autoselect mode. The system can then read some useful codes such as manufacturer and device ID from the internal registers on DQ7 - DQ0. Standard read cycle timings apply in this mode. In the Autoselect mode, the following four informations can be accessed through either autoselect command method or A9 high-voltage autoselect method. Refer to the Table 2. - Manufacturer ID - Device ID - Security Sector Lock-indicator - Sector protection verify Flash memory, enabling the system to read the boot-up firmware from the Flash memory.Refer to the AC Characteristics tables for RESET# parameters and to Fig. 19 for the timing diagram. SECTOR GROUP PROTECTION The ES29LV320 features hardware sector group protection. A sector group consists of two or more adjacent sectors that are protected or unprotected at the same time. In the device, sector protection is performed on the group of sectors previously defined in the Table 3-4. Once after a group of sectors are protected, any program or erase operation is not allowed in the protected sector group. The previously protected sectors must be unprotected by one of the unprotect methods provided here before changing data in those sectors. Sector protection can be implemented via two methods. - In-system protection - A9 High-voltage protection To check whether the sector group protection was successfully executed or not, another operation called “protect verification” needs to be performed after the protection operation on a group of sectors. All protection and protect verifications provided in the device are summarized in detail at the Table 1. Hardware Device Reset ( RESET# ) The RESET# pin provides a hardware method of resetting the device to read array data. When the RESET# pin is driven low for at least a period of tRP , the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once after the device is ready to accept another command sequence, to ensure data integrity. CMOS Standby during Device Reset Current is reduced for the duration of the RESET# pulse. When RESET# is held at Vss + 0.3V, the device draws the greatly reduced CMOS standby current ( ICC4 ). If RESET# is held at VIL but not within Vss+0.3V, the standby current will be greater. In-System Protection “In-system protection”, the primary method, requires VID (11.5V~12.5V) on the RESET# with A6=0, A1=1, and A0=0. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. Refer to Fig. 29 for timing diagram and Fig. 3 for the protection algorithm. RY/BY# and Terminating Operations If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the internal reset operation is completed, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is completed. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is “1”), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data after the RESET# pin returns to VIH, which requires a time of tRH. A9 High-Voltage Protection “High-voltage protection”, the alternate method intended only for programming equipment, must force VID (11.5~12.5V) on address pin A9 and control pin OE# with A6=0, A1=1 and A0=0. Refer to Fig. 31 for timing diagram and Fig. 5 for the protection algorithm. SECTOR UNPROTECTION The previously protected sectors must be unprotected before modifying any data in the sectors. The sector unprotection algorithm unprotects all sectors in parallel. All unprotected sectors must first 8 Rev. 2D Jan 5, 2006 RESET# tied to the System Reset The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the ES29LV320D E S II ES Excel Semiconductor inc. be protected prior to the first sector unprotection write cycle to avoid any over-erase due to the intrinsic erase characteristics of the protection cell. After the unprotection operation, all previously protected sectors will need to be individually re-protected. Standard microprocessor bus cycle timings are used in the unprotection and unprotect verification operations. Three unprotect methods are provided in the ES29LV320 device. All unprotection and unprotect verification cycles are summarized in detail at the Table 1. - In-system unprotection - A9 High-voltage unprotection - Temporary sector unprotection If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the two “outermost” 8Kbytes boot sectors independently of whether those sectors were protected or unprotected using the method described in “Sector Group Protection and Unprotection”. The two outermost of 8 Kbyte boot sectors are the two sectors containing the lowest addresses in a bottom-bootconfigured device, or the two sectors containing the highest addresses in a top-boot-configured device. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the two outermost 8 Kbyte boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these two sectors depends on whether they were last protected or unprotected using the method described in “Sector Group Protection and Unprotection”. Note that the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. In-System Unprotection “In-system unprotection”, the primary method, requires VID (11.5V~12.5V) on the RESET# with A6=1, A1=1, and A0=0. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. Refer to Fig. 29 for timing diagram and Fig. 4 for the unprotection algorithm. A9 High-Voltage Unprotection “High-voltage unprotection”, the alternate method intended only for programming equipment, must force VID (11.5~12.5V) on address pin A9 and control pin OE# with A6=1, A1=1 and A0=0. Refer to Fig. 32 for timing diagram and Fig. 6 for the unprotection algorithm. START RESET# = VID (Note 1) Temporary Sector Unprotect This feature allows temporary unprotection of previously protected sectors to change data in-system. The Sector Unprotect mode is activated by setting the RESET# pin to VID (11.5V-12.5V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are protected again. Fig. 1 shows the algorithm, and Fig. 27 shows the timing diagrams for this feature. Perform Erase or Program Operations RESET# = VIH Temporary Sector Unprotect Completed (Note 2) Notes: 1. All protected sectors are unprotected (If WP#/ACC = VIL, outermost boot sectors will remain protected). 2. All previously protected sectors are protected once again. WRITE PROTECT ( WP# ) The Write Protect function provides a hardware method of protecting certain boot sectors without using VID. This function is one of two provided by the WP#/ACC pin. Figure 1. Temporary Sector Unprotect Operation 9 ES29LV320D Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. SECURITY SECTOR The security sector of the ES29LV320 device provides an extra flash memory space that enables permanent part identification through an Electronic Serial Number (ESN). The security sector uses a security lock-Indicator Bit (DQ7) to indicate whether or not the security sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. Note that the ES29LV320 has a security sector size of 256 bytes. - A random, secure ESN (16 bytes ) only - Customer code through the ESI’s Special-Code service - Both a random, secure ESN and customer code through the ESI’s Special-Code service. ESN ( Electronic Serial Number ) In devices that have an ESN, a Bottom Boot device will have the 16-byte (8-word) ESN in sector 0 at addresses 000000h-00000Fh in byte mode (or 000000h-000007h in word mode). In the Top Boot device the ESN will be in sector 70 at addresses 3FFF00h-3FFF0Fh in byte mode (or 1FFF80h1FFF87h in word mode). Note that in upcoming top boot versions of this device, the ESN will be located in sector 70 at addresses 3FFF00h-3FFF0Fh in byte mode (or 1FFF80h-1FFF87h in word mode). Security Lock-Indicator Bit (DQ7) In the device, the security sector can be provided in either factory locked version or customer lockable version. The factory-locked version is always protected when shipped from the factory, and has the security lock-Indicator Bit permanently set to a “1”. The customer-lockable version is shipped with the security sector unprotected, allowing customers to utilize the sector in any manner they choose. The customer-lockable version has the security lockIndicator Bit permanently set to a “0”. Thus, the security lock-Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. ESI’s Special-Code Service Customers may opt to have their code programmed by ESI through the ESI’s Special-Code service. ESI programs the customer’s code, with or without the random ESN. The devices are then shipped from ESI’s factory with the Security Sector permanently locked. Contact an ESI representative for details on using ESI’s Special-Code service. Customer-Lockable Device The customer lockable version allows the security sector to be freely programmed or erased and then permanently locked. Note that the ES29LV320 has a security sector size of 256 bytes (128 words). Note that the accelerated programming (ACC) and unlock bypass functions are not available when programming the security sector. Access to the Security Sector The security sector can be accessed through a command sequence: Enter security and Exit security sector commands. After the system has written the Enter security sector command sequence, it may read the security sector by using the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit security sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device returns to read mode in which the normal boot sectors can be accessed, instead of the security sector. Protection of the Security Sector The security sector area can be protected using the following procedures: Write the three-cycle “Enter security sector command” sequence, and then following the in-system sector protect algorithm as shown in Fig. 2, except that RESET# may be at either VIH or VID. This allows in-system protection of the security sector without raising any device pin to a high voltage. Note that this method is only applicable to the security sector. To verify the protect/ unprotect status of the security sector. follow the algorithm shown in Fig. 2. Factory-Locked Device In a factory-locked device, the security sector is protected when the device is shipped from the factory. The security sector cannot be modified in any way. The device is available preprogrammed with one of the following: ES29LV320D 10 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. Start If data=00h, security sector is unprotected. If data=01h, security sector is protected can only occur after successful completion of specific command sequences. And several features are incorporated to prevent inadvertent write cycles resulting from Vcc power-up and power-down transition or system noise. RESET# = VIH or VID Low Vcc Write inhibit When Vcc is less than VLKO, the device does not accept any write cycles. This protects data during Vcc power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to the read mode. Subsequent writes are ignored until Vcc is greater than VLKO. The system must provide proper signals to the control pins to prevent unintentional writes when Vcc is greater than VLKO. Wait 1us Remove VIH or VID from RESET# Write 60h to any address Write reset command Write 40h to security sector address with A6=0, A1=1,A0=0 Security sector Protect Verify complete Write Pulse “Glitch” Protection Noise pulses of less than 5ns (typical) on OE#, CE# or WE# do not initiate a write cycle. Read from security sector address with A6=0,A1=1,A0=0 Logical inhibit Figure 2. Security Sector Protect Verify Write cycles are inhibited by holding any one of OE#=VIL, CE#=VIH or WE#=VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. Exit from the Security Sector Once the Security Sector is locked protected and verified, the system must write the Exit Security Sector Region command sequence to return to reading and writing the remainder of the array. Power-up Write Inhibit If WE#=CE#=VIL and OE#=VIH during power up, the device does not accept any commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on power-up. Caution for the Security Sector Protection The security sector protection must be used with caution since, once protected, there is no procedure available for unprotecting the security sector area and none of the bits in the security sector memory space can be modified in any way. HARDWARE DATA PROTECTION The ES29LV320 device provides some protection measures against accidental erasure or programming caused by spurious system level signals that may exist during power transition. During powerup, all internal registers and latches in the device are cleared and the device automatically resets to the read mode. In addition, with its internal state machine built-in the device, any alteration of the memory contents or any initiation of new operation 11 ES29LV320D Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc.

Common Flash Memory Interface (CFI) CFI is supported in the ES29LV320 device. The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI query command, 98h, to address 55h in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 5-8. To terminate reading CFI data, the system must write the reset command.The CFI query command can be written to the system when the device is in the autoselect mode or the erase-suspend-read mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 5-8. When the reset command is written, the device returns respectively to the read mode or erase-suspend-read mode. Table 5.

COMMAND DEFINITIONS Writing specific address and data commands or sequences into the command register initiates device operations. Table 9 defines the valid register command sequences. Note that writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is required to return the device to normal operation. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to the AC Characteristics section for timing diagrams. the Device Bus Operations section for more information.The Read-Only Operations table provides the read parameters, and Fig. 18 shows the timing diagram RESET COMMAND Writing the reset command resets the device to the read or erase-suspend-read mode. Address bits are don’t cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to which the system was writing to the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to which the system was writing to the read mode. If the program command sequence is written to a sector that is in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If the device entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns the device to the erase-suspendread mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the read mode (or erase-suspend-read mode if the device was in Erase-Suspend). 22 Rev. 2D Jan 5, 2006 READING ARRAY DATA The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information. The system must issue the reset command to return the device to the read (or erase-suspend-read) mode if DQ5 goes high during an active program or erase operation, or if the device is in the autoselect mode. See the next section, Reset Command, for more information. See also Requirements for Reading Array Data in ES29LV320D E S II ES Excel Semiconductor inc. Command Definitions Table 9.

ES29LV320D 23 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. AUTOSELECT COMMAND The autoselect command sequence allows the host system to access the manufacturer and device codes, and determine whether or not a sector is protected, including information about factorylocked or customer lockable version. Identifier Code Manufacturer ID Device ID SECURITY SECTOR COMMAND In the ES29LV320 device, the security sector region (256 bytes) provides a secured data area containing a random, sixteen-byte electronic serial number(ESN) or customer’s security codes. The security sector region can be accessed by issuing the three-cycle Enter Security Sector command sequence. The device continues to access the security sector region until the system issues the four-cycle Exit Security Sector command sequence. The Exit Security Sector command sequence returns the device to normal operation. Table 9 shows the address and data requirements for both command sequences. Note that the accelerated programming function by WP#ACC and unlock bypass mode are not available when the device has entered the security sector. Refer to the Fig. 7 for the security sector operation.

This method is an alternative to “A9 high-voltage method” shown in Table 2, which is intended for PROM programmers and requires VID on address pin A9. The autoselect command sequence may be written to an address within sector that is either in the read mode or erase-suspend-read mode. The auto-select command may not be written while the device is actively programming or erasing. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the autoselect command. The device then enters the autoselect mode. The system may read at any address any number of times without initiating another autoselect command sequence. Once after the device enters the auto-select mode, the manufacture ID code ( 4Ah ) can be accessed by one of two ways. Just one read cycle ( with A6, A1 and A0 = 0 ) can be used. Or four consecutive read cycles ( with A6 = 1 and A1, A0 = 0 ) for continuation codes (7Fh) and then another last cycle for the code (4Ah) (with A6, A1 and A0 = 0) can be used for reading the manufacturer code. - 4Ah (one-cycle read) - 7Fh 7Fh 7Fh 7Fh 4Ah (Five-cycle read) Read Mode Enter Security Sector Command Program, Erase or Protection Exit Security Sector Command Read Mode Figure 7. Security Sector Operation The system must write the reset command to return to the read mode (or erase-suspend-read mode if the device was previously in Erase Suspend). ES29LV320D 24 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. BYTE / WORD PROGRAM The system may program the device by word or byte, depending on the state of the BYTE# pin. Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Table 9 shows the address and data requirements for the byte program command sequence. Note that the autoselect, commands related with the security sector, and CFI modes are unavailable while a programming operation is in progress. Program Status Bits : DQ7, DQ6 or RY/BY# When the Embedded Program algorithm is complete, the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/BY#. Refer to the Write Operation Status section Table 10 for information on these status bits. Any Commands Ignored during Programming Operation Any commands written to the device during the Embedded Program algorithm are ignored. Note that a hardware reset can immediately terminates the program operation. The program command sequence should be reinitiated once the device has returned to the read mode, to ensure data integrity. Programming from “0” back to “1” Programming is allowed in any sequence and across sector boundaries. But a bit cannot be programmed from “0” back to a ”1”. Attempting to do so may cause the device to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read will show that the data is still “0”. Only erase operations can convert a “0” to a “1” START Write Program Command Sequence Embedded Program algorithm in progress Data Poll from System Unlock Bypass In the ES29LV320 device, an unlock bypass program mode is provided for faster programming operation. In this mode, two cycles of program command sequences can be saved. To enter this mode, an unlock bypass enter command should be first written to the system. The unlock bypass enter command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock-bypass program mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program set-up command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Table 9 shows the requirements for the command sequence. No Verify Data? Yes No Increment Address Last Address? Yes Programming Completed Note: See Table 9 for program command sequence Figure 8. Program Operation ES29LV320D 25 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. During the unlock-bypass mode, only the unlockbypass program and unlock-bypass reset commands are valid. To exit the unlock-bypass mode, the system must issue the two-cycle unlock-bypass reset command sequence. The first cycle must contain the data 90h. The second cycle need to only contain the data 00h. The device then returns to the read mode. - Unlock Bypass Enter Command - Unlock Bypass Reset Command - Unlock Bypass Program Command Table 9 shows the address and data requirements for the chip erase command sequence. Note that the autoselect, security sector, and CFI modes are unavailable while an erase operation is in progress Erase Status Bits : DQ7, DQ6, DQ2, or RY/BY# When the Embedded Erase algorithm is complete, the device returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. Refer to the Write Operation Status section Table 10 for information on these status bits. Unlock Bypass Program during WP#/ACC Accelerated Program Mode The device offers accelerated program operations through the WP#/ACC pin. When the system asserts VHH on the WP#/ACC pin, the device automatically enters the unlock bypass mode. The system may then write the two-cycle unlock bypass program command sequence. The device uses the higher voltage on the WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not be at VHH in any operation other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Fig. 8 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Fig. 22 for timing diagrams. Commands Ignored during Erase Operation Any command written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the chip erase command sequence should be reinitiated once the device has returned to reading array data. to ensure data integrity. Fig. 9 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Fig. 23 section for timing diagrams. SECTOR ERASE COMMAND By using a sector erase command, a single sector or multiple sectors can be erased. The sector erase command is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. Table 9 shows the address and data requirements for the sector erase command sequence. Note that the autoselect, security sector, and CFI modes are unavailable while an erase operation is in progress. CHIP ERASE COMMAND To erase the entire memory, a chip erase command is used. This command is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The chip erase command erases the entire memory including all other sectors except the protected sectors, but the internal erase operation is performed on a single sector base. Embedded Sector Erase Algorithm The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings these operations. Embedded Erase Algorithm The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. 26 ES29LV320D Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. Sector Erase Time-out Window and DQ3 After the command sequence is written, a sector erase time-out of 50us occurs. During the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 us, otherwise the last address and command may not be accepted, and erasure may begin. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be reenabled after the last Sector Erase command is written. The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3:Sector Erase Timer.). The time-out begins from the rising edge of the final WE# pulse in the command sequence. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to the read mode. The system must rewrite the command sequence and any additional addresses and commands. Status Bits : DQ7,DQ6,DQ2, or RY/BY# When the Sector Erase Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. Note that while the Embedded Erase operation is in progress, the system can read data from the non-erasing sector. The system can determine the status of the erase operation by reading DQ7,DQ6,DQ2, or RY/BY# in the erasing sector. Refer to the Write Operation Status section Table 10 for information on these status bits. Valid Command during Sector Erase Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. Fig. 9 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Fig. 23 section for timing diagrams. ERASE SUSPEND/ERASE RESUME START Write Erase Command Sequence (Notes 1,2) An erase operation is a long-time operation so that two useful commands are provided in the ES29LV320 device Erase Suspend and Erase Resume Commands. Through the two commands, erase operation can be suspended for a while and the suspended operation can be resumed later when it is required. While the erase is suspended, read or program operations can be performed by the system. Embedded Erase algorithm in progress No Data Poll to Erasing Bank from System Erase Suspend Command, (B0h) The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50us time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20us to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the timeout period and suspends the erase operation. 27 No Data = FFh? Yes Erasure Completed Notes: 1. See Table 9 for erase command sequence 2. See the section on DQ3 for information on the sector erase timer Figure 9. Erase Operation ES29LV320D Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. Read and Program during Erase-SuspendRead Mode After the erase operation has been suspended, the device enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device “erase suspends” all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Write Operation Status section for information on these status bits (Table 10). After an erase-suspended program operation is complete, the device returns to the erase-suspendread mode. The system can determine the status for the program operation using the DQ7 or DQ6 status bits, just as in the standard Byte Program operation. Refer to the Write Operation Status section for more information. Autoselect during Erase-Suspend- Read Mode In the erase-suspend-read mode, the system can also issue the autoselected command sequence. Refer to the Autoselect Mode and Autoselect Command Sequence section for details (Table 9). Erase Resume Command To resume the sector erase operation, the system must write the Erase Resume command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing. ES29LV320D 28 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc.

Command Diagram ES29LV320D 29 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. WRITE OPERATION STATUS In the ES29LV320 device, several bits are provided to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, DQ7 and RY/BY#. Table 10 and the following subsections describe the function of these bits. DQ7 and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. The device also provides a hardware-based output signal, RY/ BY#, to determine whether an Embedded Program or Erase operation is in progress or has been completed. Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# polling produces a “1” on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. Erase on the Protected Sectors After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 1.8us, then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. DQ7 (DATA# POLLING) The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether a device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. Data# Polling Algorithm Just prior to the completion of an Embedded Program or Ease operation, DQ7 may change asynchronously with DQ0-DQ6 while Output Enable(OE#) is asserted low. That is, this device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ0-DQ7 will appear on successive read cycles. Table 10 shows the outputs for Data# Polling on DQ7. Fig. 11 shows the Data# Polling algorithm. Fig. 24 in the AC Characteristics section shows the Data# Polling timing diagram. During Programming During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately 250ns, then the device returns to the read mode. During Erase During the Embedded Erase algorithm, Data# Polling produces a “0” on DQ7. When the Embedded ES29LV320D 30 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. START Read DQ7-DQ0 Addr = VA DQ7 = Data ? No No DQ5 = 1 ? Yes Read DQ7-DQ0 Addr = VA Yes Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence ( prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, DQ6 stops toggling. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7(see the subsection on DQ7:Data# Polling). DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 10 shows the outputs for Toggle Bit I on DQ6. Fig. 12 shows the toggle bit algorithm. Fig. 25 in the “AC Characteristics” section shows the toggle bit timing diagrams. Fig. 26 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2 : (Toggle Bit II). Yes DQ7 = Data ? No FAIL PASS Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address in any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5 Figure 11. Data# Polling Algorithm Toggling on the Protected Sectors RY/BY# ( READY/BUSY# ) The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an opendrain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to Vcc. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read mode, the standby mode, or in the erase-suspend-read mode. Table 10 shows the outputs for RY/BY#. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 1.8us, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. If a program address falls within a protected sector, DQ6 toggles for approximately 250ns after the program command sequence is written, then returns to reading array data. DQ2 ( TOGGLE BIT II ) The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence DQ2 DQ6 ( TOGGLE BIT I ) Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the ES29LV320D 31 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erasesuspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 10 to compare outputs for DQ2 and DQ6. Fig. 12 shows the toggle bit algorithm in flowchart form, and the section “DQ2: Toggle Bit II” explains the algorithm. See also the DQ6: Toggle Bit I subsection. Fig. 25 shows the toggle bit timing diagram. Fig. 26 shows how differently DQ2 operates compared with DQ6. START Read DQ7-DQ0 Read DQ7-DQ0 Toggle Bit = Toggle ? Yes No DQ5 = 1 ? Yes Read DQ7-DQ0 Twice No Reading Toggle Bits DQ6/DQ2 Refer to Fig. 12 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, this system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of Fig. 12). Toggle Bit = Toggle ? Yes Program/Erase Operation Not Complete, Write Reset Command No Program/Erase Operation Complete Note: The system should recheck the toggle bit even if DQ5 = “1” because the toggle bit may stop toggling as DQ5 changes to “1”. See the subsections on DQ6 and DQ2 for more information. Figure 12. Toggle Bit Algorithm ES29LV320D 32 Rev. 2D Jan 5, 2006 E S II ES Excel Semiconductor inc. DQ5 ( EXCEEDED TIMING LIMITS ) DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a “1”, indicating that the program or erase cycle was not successfully completed. The device may output a “1” on DQ5 if the system tries to program a “1” to a location that was previously programmed to “0” Only an erase operation can change a “0” back to a “1”. Under this condition, the device halts the operation, and when the timing limit has been exceeded, DQ5 produces a ”1”. Under both these conditions, the system must write the reset command to return to the read mode. DQ3 ( SECTOR ERASE TIMER ) After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. (The sector erase time does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is complete, DQ3 switches from a “0” to a”1”. If the time between additional sector erase commands from the system can be assumed to be less than 50us, the system need not monitor DQ3. See also the Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is “1”, the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erasure operation is complete. If DQ3 is “0”, the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. In Table 10, DQ3 status operation is well defined and summarized with other status bits, DQ7, DQ6, DQ5, and DQ2. Table 10.
