AM29LV004 - AMD

AM29LV004 4 Megabit (512 K x 8-Bit) CMOS 3.0 Volt-only Boot Sector Flash Memory

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 the device. The.

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 combination 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.
