GENERAL DESCRIPTION
The Am29LV001B has a boot sector architecture. The byte-wide (x8) data appears on DQ7-DQ0. All read, erase, and program operations are accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers. The standard Am29LV001B offers access times of 45, 55, 70, and 90 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 device requires only a single power supply (2.7 V–3.6V) for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The Am29LV001B 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 that controls the erase and programming circuitry.
