Product Summary
The AM29LV040B-70ED is a single power supply, 4 Mbit, 3.0 Volt-only Flash memory device organized as 524,288 bytes. The data appears on DQ0-DQ7. The AM29LV040B-70ED is available in 32-pin PLCC and 32-pin TSOP packages. All read, erase, and program operations are accomplished using only a single power supply. The AM29LV040B-70ED can also be programmed in standard EPROM programmers. The AM29LV040B-70ED offers access times of 60, 70, 90, and 120 ns allowing high speed microprocessors to operate without wait states. To eliminate bus contention, the AM29LV040B-70ED has separate control pins—chip enable (CE#), write enable (WE#), and output enable (OE#)—to control normal read and write operations. The AM29LV040B-70ED requires only a single power supply (2.7V–3.6V) for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.
