PRELIMINARY  
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  
Minimum 1,000,000 program/erase cycles per  
sector guaranteed  
Package options  
— 40-pin TSOP  
— Minimizes system level power requirements  
Manufactured on 0.35 µm process technology  
— Compatible with 0.5 µm Am29F080 device  
— 44-pin SO  
High performance  
Compatible with JEDEC standards  
— Access times as fast as 70 ns  
— Pinout and software compatible with  
single-power-supply Flash standard  
Low power consumption  
— 25 mA typical active read current  
— 30 mA typical program/erase current  
— Superior inadvertent write protection  
Data# Polling and toggle bits  
— 1 µA typical standby current (standard access  
time to active mode)  
— Provides a software method of detecting  
program or erase cycle completion  
Flexible sector architecture  
— 16 uniform sectors of 64 Kbytes each  
— Any combination of sectors can be erased.  
— Supports full chip erase  
Ready/Busy# output (RY/BY#)  
— Provides a hardware method for detecting  
program or erase cycle completion  
Erase Suspend/Erase Resume  
— Group sector protection:  
— Suspends a sector erase operation to read data  
from, or program data to, a non-erasing sector,  
then resumes the erase operation  
A hardware method of locking sector groups to  
prevent any program or erase operations within  
that sector group  
Hardware reset pin (RESET#)  
Temporary Sector Group Unprotect allows code  
changes in previously locked sectors  
— Resets internal state machine to the read mode  
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
