AM29LV002 Datasheet | AMD

features : A hardware method of locking a sector to prevent any program or erase operations within that sector Temporary Sector Unprotect feature allows code changes in previously locked sectors s Top or bottom boot block configurations available s Embedded Algorithms - Embedded Erase algorithms automatically preprogram and erase the entire chip or any bination of designated sectors - Embedded Program algorithms automatically write and verify bytes or words at specified addresses s Typical 1,000,000 write cycles per sector (100,000 cycles minimum guaranteed) s Package option - 40-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 operation pletion s Ready/Busy# pin (RY/BY#) - Provides a hardware method of detecting program or erase cycle pletion s Erase Suspend/Erase Resume feature - Suspends an erase operation to read data from, or program data to, a sector that is not being erased, then resumes the erase operation s Hardware reset pin (RESET#) - Hardware method to reset the device to the read mode Publication# 21191 Rev: C Amendment/+2 Issue Date: March 1998 . P R E L I M I N A R Y GENERAL DESCRIPTION The Am29LV002 is a 2 Mbit, 3.0 Volt-only Flash memory organized as 262,144 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7- DQ0. All read, program, and erase operations are acplished using only a single power supply. The device can also be programmed in standard EPROM programmers. The standard device offers access times of 90, 100, 120, 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 device requires only a single 3.0 volt power supply for both read and write functions. Internally...
