GENERAL DESCRIPTION
Eight bits of data appear on DQ0–DQ7 in byte mode; in word mode 16 bits appear on DQ0–DQ15. This device is designed to be programmed in-system with the standard system 5.0 Volt VCC supply. A VPP of 12.0 volts is not required for program or erase operations. The device can also be programmed in standard EPROM programmers. 8/18/97 The standard Am29F800 offers access times of 70 ns, 90 ns, 120 ns, and 150 ns, allowing high-speed microprocessors to operate without wait states. To eliminate bus contention, the device has separate chip enable (CE), write enable (WE), and output enable (OE) controls. The Am29F800 is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and program circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations.
