Publication# 22140 Rev: A Amendment/0 Issue Date: April 1998 ADVANCE INFORMATION GENERAL DESCRIPTION The Am29LV010B is a 1 Mbit, 3.0 Volt-only Flash memory device organized as 131,072 bytes. The Am29LV010B has a uniform sector architecture. The device is offered in 32-pin PLCC and 32-pin TSOP packages. 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 Am29LV010B offers access times of 45, 55, 70, and 120 ns (90 and 100 ns parts are also available), 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 device 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. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm—an internal algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and e.
