Notice to Users Z-WORLD PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE-SUPPORT DEVICES OR SYSTEMS UNLESS A SPECIFIC WRITTEN AGREEMENT REGARDING SUCH INTENDED USE IS ENTERED INTO BETWEEN THE CUSTOMER AND Z-WORLD PRIOR TO USE. Life-support devices or systems are devices or systems intended for surgical implantation into the body or to sustain life, and whose failure to perform, when properly used in accordance with instructions for use provided in the labeling and user’s manual, can be reasonably expected to result in significant injury. No complex software or hardware system is perfect. Bugs are always present in a system of any size. In order to prevent danger to life or property, it is the responsibility of the system designer to incorporate redundant protective mechanisms appropriate to the risk involved. All Z-World products are 100 percent functionally tested. Additional testing may include visual quality control inspections or mechanical defects analyzer inspections. Specifications are based on characterization of tested sample units rather than testing over temperature and voltage of each unit. Z-World may qualify components to operate within a range of parameters that is different from the manufacturer’s recommended range. This strategy is believed to be more economical and effective. Additional testing or burn-in of an individual unit is available by special arrangement.

Single-board computers equipped with the Rabbit 2000 processor can use the SF1000 with either a synchronous serial peripheral interface (SPI) or an emulated SPI via parallel I/O ports. Zilog Z180-based single-board computers must use the emulated SPI method. Two SF1000 models are presently offered, as shown in Table 1. Table 1. SF1000 Models Model Flash Memory Size SF1000 8MB SF1010 4MB Larger memories will be possible in the future when parts become available. These serial flash cards are ideal for applications that require the temporary storage of large amounts of data. This data can be retrieved or downloaded to another system via the controlling single-board computer using TCP/IP or serial communication, or the card itself may be removed to facilitate transferring the data to another location. User’s Manual 5 6 SF1000 GETTING STARTED Headers The SF1000 comes with a 10-pin, 2 mm, 5×2 header located at J1 as shown in Figure 1. Headers, either plugs or sockets, SMT or through-hole, may also be installed at J2 or J3. The pinouts for these positions are identical, and allow for a connecting cable to be hooked up in different ways. There is also a location at J4 for a 7-pin in-line header or socket with 0.1" spacing. Position 6 at J4 is not used, which allows this connection to be keyed. J1 5×2 header installed Flash EPROM J4 J3 J2 optional 5×2 headers optional 7×1 in-line header Figure 1. User Connection Points to SF1000 User’s Manual 7 Pinout Only six connections are required to interface the SF1000 with a Z-World single-board computer: • +5 V • Ground • Chip Select input • Serial Clock Input • Serial Data Input • Serial Data Output. This output is inverted because the serial flash is a 3 V part and the signal is converted to 5 V via an inverting transistor buffer. Figure 2 shows the pinouts for the SF1000 header locations.

Table 2 lists the connections. Table 2.

While Serial Port B is the recommended port for connecting the SF1000 serial flash card, the programming port (Serial Port A), which is compatible with the header pinout on header J1 on the SF1000, or a parallel I/O port may also be used. A connector cable is available from Z-World if you wish to connect the SF1000 to the programming port (Serial Port A) on your Rabbit-based board. ! Note that the programming port (Serial Port A) will not be available for application development and debugging if it is used to connect the SF1000 serial flash card. $ Refer to the “Programming Information” section of the “Software” chapter for details of the software associated with your choice of connections. User’s Manual 9 A synchronous Serial Port B is not available on the BL2000, and so the following parallel-port connections are recommended instead. Table 3.

SF1000 SOFTWARE The SF1000 serial flash expansion card implements a flash memory chip with a single, large, linear address space. It is up to the user to maintain appropriate information within the program in order to store and retrieve data in the flash memory. The flash memory chip consists of a series of “sectors.” The size of each sector is the same within a given chip, but can vary from one chip to another. A sector also contains extra bytes that are not made available to the user. Some of these bytes are used by the driver as follows: • a fixed sync value, indicating that the sector has been written to at least once, • a version number, and • a long integer value for the number of times the sector has been written. The user should keep in mind that a flash memory chip has a limited number of write cycles per sector, and that an entire sector must be written at a time. The chips used in the SF1000 serial flash cards are specified at 50,000 write cycles typical. The most efficient usage dictates that the user “block” all writing to the flash memory so that only full sectors are written. More than one SF1000 serial flash card may be used in the control system built around the Z-World single-board computer. Users have to write their own CS_enable/CS_disable functions to control the chip select signals on the SF1000 serial flash cards. The only restriction is that all the SF1000 serial flash cards have the same size of flash memory chip, i.e., 4M or 8M. User’s Manual 15 Dynamic C Z-World’s Dynamic C integrated development software is used to add API functions from the SF1000.LIB library to your program. The SF1000.LIB library is available in Dynamic C Premier for Rabbit-based boards and in DC 32 for selected Z180-based boards. SF1000.LIB Library Functions The following API functions are available in the Dynamic C SF1000.LIB library. These functions are blocking functions, but do not disable interrupts. The functions are not re-entrant. • int SF1000Init ( void ); Minimum setup needed to verify correct flash operation. PARAMETERS: None. RETURN VALUES: 0 = success -1 = invalid density value read -2 = unknown response -3 = maybe no SF1000? GLOBALS DEFINED: int int int int SF1000_Density_Value SF1000_Sector_size SF1000_Block_size SF1000_Nbr_of_Blocks • int SF1000Write ( long FlashAddrDest, void* Data, int ByteCount ); Write a block of data to the flash. PARAMETERS: 1 = (long) address of destination 2 = (void*) source RAM starting address 3 = (int) number of bytes to write RETURN VALUES: 0 = success -1 = illegal byte count -2 = illegal flash address 16 SF1000 • int SF1000Read ( long FlashAddrSource, void* Data, int ByteCount ); Read a block of data from the flash. PARAMETERS: 1 = (long) address of source 2 = (void*) destination RAM starting address 3 = (int) number of bytes to write RETURN VALUES: 0 = success -1 = illegal byte count -2 = illegal flash address • long SF1000CheckWrites ( int Block ); Read the number of times that a block has been written. PARAMETER: (int) block number (0 relative) RETURN VALUE: the number of times the block has been written.
