Am29F080B

8 Megabit (1 M x 8-Bit)

CMOS 5.0 Volt-only, Uniform Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

■ 5.0 V ± 10%, single power supply operation

— Minimizes system level power requirements

■ Manufactured on 0.32 µm process technology

— Compatible with 0.5 µm Am29F080 device

■ High performance

— Access times as fast as 55 ns

■ Low power consumption

— 25 mA typical active read current

— 30 mA typical program/erase current

— 1 µA typical standby current (standard access

time to active mode)

■ Flexible sector architecture

— 16 uniform sectors of 64 Kbytes each

— Any combination of sectors can be erased.

— Supports full chip erase

— Group sector protection:

A hardware method of locking sector groups to

prevent any program or erase operations within

that sector group

Temporary Sector Group Unprotect allows code

changes in previously locked sectors

■ 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

■ Minimum 1,000,000 program/erase cycles per

sector guaranteed

■ 20-year data retention at 125°C

— Reliable operation for the life of the system

■ Package options

— 40-pin TSOP

— 44-pin SO

■ Compatible with JEDEC standards

— Pinout and software compatible with

single-power-supply Flash standard

— Superior inadvertent write protection

■ Data# Polling and toggle bits

— Provides a software method of detecting program

or erase cycle completion

■ Ready/Busy# output (RY/BY#)

— Provides a hardware method for detecting

program or erase cycle completion

■ 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

■ Hardware reset pin (RESET#)

— Resets internal state machine to the read mode

■ Command sequence optimized for mass storage

— Specific addresses not required for unlock cycles
