Overview
PRELIMINARY Am29F040B 4 Megabit (512 K x 8-Bit) CMOS 5.
0 Volt-only, Uniform Sector Flash Memory Distinctive Characteristics s 5.
0 V ± 10% for read and write operations — Minimizes system level power requirements s Manufactured on 0.
35 µm process technology — Compatible with 0.
5 µm Am29F040 device s High performance — Access times as fast as 55 ns s Low power consumption — 20 mA typical active read current — 30 mA typical program/erase current — 1 µA typical standby current (standard access time to active mode) s Flexible sector architecture — 8 uniform sectors of 64 Kbytes each — Any combination of sectors can be erased — Supports full chip erase — Sector protection: A hardware method of locking sectors to prevent any program or erase operations within that sector 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 bytes at specified addresses s Minimum 1,000,000 program/erase cycles per sector guaranteed s Package options — 32-pin PLCC, TSOP, or PDIP s Compatible with JEDEC standards — Pinout and software compatible with single-power-supply Flash standard — Superior inadvertent write protection s Data# Polling and toggle bits — Provides a software method of detecting program or erase cycle completion s Erase Suspend/Erase Resume — Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation Publication# 21445 Rev: B Amendment/+2 Issue Date: April 1998 P R E L I M I N A R Y GENERAL DESCRIPTION The Am29F040B is a 4 Mbit, 5.
0 volt-only Flash memory organized as 524,288 Kbytes of 8 bits each.
The 512 Kbytes of data are divided into eight sectors of 64 Kbytes each for flexible erase capability.
The 8 bits of data appear on DQ0–DQ7.
The Am29F040B is offered in 32-pin PLCC, TSOP, and PDIP packages.
This device is designed to be programmed in-system wi...
