GENERAL DESCRIPTION The Austin Semiconductor, Inc. AS28C010 is a 1 Megabit CMOS Electrically Erasable Programmable Read Only Memory (EEPROM) organized as 131, 072 x 8 bits. The AS28C010 is capable of in system electrical Byte and Page reprogrammability. The AS28C010 achieves high speed access, low power consumption, and a high level of reliability by employing advanced CMOS process and circuitry technology. This device has a 256-Byte Page Programming function to make its erase and write operations faster. The AS28C010 features Data Polling and a toggle signal to indicate completion of erase and programming operations. This EEPROM provides several levels of data protection., in AS28C010 Rev. 1.5 5/06 addition to noise protection on the WE signal and write inhibit during power on and off. Software data protection is implemented using JEDEC Optional Standard algorithm. The AS28C010 is designed for high reliability in the most demanding applications. Data retention is specified for 100 years and erase/write endurance is guaranteed to a minimum of 100,000 cycles in the Page Mode and 10,000 cycles in the Byte Mode.

FUNCTIONAL DESCRIPTION READ Read operations are initiated by both OE\ and CE\ LOW. The read operation is terminated by either CE\ or OE\ returning HIGH. This two line control architecture eliminates bus contention in a system environment. The data bus will be in a high impedance state when either OE\ or CE\ is HIGH. Figure 1: Status Bit Assignment I/O DP TB 5 4 3 2 1 0 AS28C010 RESERVED TOGGLE BIT DATA\ POLLING DATA\ POLLING The AS28C010 features DATA\ Polling as a method to indicate to the host system that the byte write or page write cycle has completed. DATA\ Polling allows a simple bit test operation to determine the status of the AS28C010, eliminating additional interrupt inputs or external hardware. During the internal programming cycle, any attempt to read the last byte written will produce the complement of that data on I/O7 (i.e., write data = 0xxx xxxx, read data = 1xxx xxxx). Once the programming cycle is complete, I/O7 will reflect true data. Note: If the AS28C010 is in the protected state and an illegal write operation is attempted DATA\ Polling will not operate. WRITE Write operations are initiated when both CE\ and WE\ are LOW and OE\ is HIGH. The AS28C010 supports both a CE\ and WE\ controlled write cycle. That is, the address is latched by the falling edge of either CE\ or WE\, whichever occurs last. Similarly, the data is latched internally by the rising edge of either CE\ or WE\, whichever occurs first. A byte write operation, once initiated, will automatically continue to completion, typically within 5ms. PAGE WRITE The page write feature of the AS28C010 allows the entire memory to be written in 5 seconds. Page write allows two to two hundred fifty-six bytes of data to be consecutively written to the AS28C010 prior to the commencement of the internal programming cycle. The host can fetch data from another device within the system during a page write operation (change the source address), but the page address (A8 through A16) for each subsequent valid write cycle to the part during this operation must be the same as the initial page address. The page write mode can be initiated during any write operation. Following the initial byte write cycle, the host can write an additional one to two hundred fifty six bytes in the same manner as the first byte was written. Each successive byte load cycle, started by the WE\ HIGH to LOW transition, must begin within 100µs of the falling edge of the preceding WE\. If a subsequent WE\ HIGH to LOW transition is not detected within 100µs, the internal automatic programming cycle will commence. There is no page write window limitation. Effectively the page write window is infinitely wide, so long as the host continues to access the device within the byte load cycle time of 100µs. TOGGLE BIT The AS28C010 also provides another method for determining when the internal write cycle is complete. During the internal programming cycle, I/O6 will toggle from HIGH to LOW and LOW to HIGH on subsequent attempts to read the device. When the internal cycle is complete the toggling will cease and the device will be accessible for additional read or write operations. WRITE The AS28C010 provides the user two write operation status bits. These can be used to optimize a system write cycle time. The status bits are mapped onto the I/O bus as shown in Figure 1.
