1 Megabit (128 K x 8-bit)

CMOS 5.0 Volt-only, Uniform Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

Single power supply operation

— 5.0 V ± 10% for read, erase, and program operations

— Simplifies system-level power requirements

Manufactured on 0.32 µm process technology

— Compatible with Am29F010 and Am29F010A

device

High performance

— 45 ns maximum access time

Low power consumption

— 12 mA typical active read current

— 30 mA typical program/erase current

— <1 µA typical standby current

Flexible sector architecture

— Eight 16 Kbyte sectors

— Any combination of sectors can be erased

— Supports full chip erase

Sector protection

— Hardware-based feature that disables/re-

enables program and erase operations in any

combination of sectors

— Sector protection/unprotection can be

implemented using standard PROM

programming equipment

Embedded Algorithms

— Embedded Erase algorithm automatically

pre-programs and erases the chip or any

combination of designated sector

— Embedded Program algorithm automatically

programs and verifies data at specified address

Erase Suspend/Resume

— Supports reading data from a sector not

being erased

Minimum 1 million erase cycles guaranteed per

sector

20-year data retention at 125°C

— Reliable operation for the life of the system

Package options

— 32-pin PLCC

— 32-pin TSOP

— 32-pin PDIP

Compatible with JEDEC standards

— Pinout and software compatible with

single-power-supply flash

— Superior inadvertent write protection

Data# Polling and Toggle Bits

— Provides a software method of detecting

program or erase cycle completion
