AM29LV004 Datasheet | AMD

features : A hardware method of locking a sector to prevent any program or erase operations within that sector Sectors can be locked via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors s Top or bottom boot block configurations available s Embedded Algorithms - Embedded Erase algorithm automatically preprograms and erases the entire chip or any bination of designated sectors - Embedded Program algorithm automatically writes and verifies data 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 - 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 reading array data This document contains information on a product under development at Advanced Micro Devices.

P R E L I M I N A R Y GENERAL DESCRIPTION The Am29LV004 is an 4 Mbit, 3.0 volt-only Flash memory organized as 524,288 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7- DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase...
