Advanced Micro Devices 

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
