AM29LV040B Datasheet | AMD

features : Hardware method of locking a sector to prevent any program or erase operations within that sector Sectors can be locked via programming equipment s Unlock Bypass Program mand - Reduces overall programming time when issuing multiple program mand sequences s Embedded Algorithms - Embedded Erase algorithms automatically preprogram and erase the entire chip or any bination of designated sectors - Embedded Program algorithms automatically writes and verifies data at specified addresses s Minimum 1,000,000 write/erase cycles guaranteed s Package option - 32-pin PLCC - 32-pin TSOP s patibility with JEDEC standards - Pinout and software patible with singlepower supply Flash - Superior inadvertent write protection s Data# Polling and toggle bits - Provides a software method of detecting program or erase cycle pletion s Erase Suspend/Resume - Supports reading data from or programming data to a sector not being erased This document contains information on a product under development at Advanced Micro Devices.

A D V A N C E I N F O R M A T I O N GENERAL DESCRIPTION The Am29LV040B 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 device is available in 32-pin PLCC and 32-pin TSOP packages. All read, erase, and program operations are acplished using only a single power supply. The device can also be programmed in standard EPROM programmers. The device offers access times of 55, 70, 90, and 120 ns allowing high speed microprocessors to operate without wait states. To eliminate bus contention, the device has separate control pins- chip enable (CE#), write enable (WE#), and output enable (OE#)- to control normal...
