PRELIMINARY

Am29F080

8 Megabit (1,048,576 x 8-Bit) CMOS 5.0 Volt-only,

Sector Erase Flash Memory

DISTINCTIVE CHARACTERISTICS

■ 5.0 Volt ±10% for read and write operations

— Minimizes system level power requirements

■ Compatible with JEDEC-standards

■ Embedded Program™ Algorithms

— Automatically programs and veriﬁes data at

speciﬁed address

■ Data Polling andToggle Bit feature for detection

— Pinout and software compatible with

single-power-supply Flash

of program or erase cycle completion

■ Ready/Busy output (RY/BY)

— Superior inadvertent write protection

— Hardware method for detection of program or

erase cycle completion

■ Package Options

— 40-pin TSOP

■ Erase Suspend/Resume

— 44-pin PSOP

— Supports reading or programming data to a

■ Minimum 100,000 write/erase cycles guaranteed

■ High performance

sector not being erased

■ Low power consumption

— 85 ns maximum access time

■ Sector erase architecture

— Uniform sectors of 64 Kbytes each

— 30 mA maximum active read current

— 60 mA maximum program/erase current

■ Enhanced power management for standby

— Any combination of sectors can be erased.

Also supports full chip erase

mode

— <1 µA typical standby current

— Standard access time from standby mode

■ Hardware RESET pin

■ Group sector protection

— Hardware method that disables any combination

of sector groups from write or erase operations

(a sector group consists of 2 adjacent sectors of

64 Kbytes each)

— Resets internal state machine to the read mode

■ Embedded Erase™ Algorithms

— Automatically preprograms and erases the chip

or any sector

GENERAL DESCRIPTION

The Am29F080 is an 8 Mbit, 5.0 Volt-only Flash mem-

ory organized as 1 Megabyte of 8 bits. The 1 Mbyte of

data is divided into 16 sectors of 64 Kbytes for ﬂexible

erase capability.The 8 bits of data will appear on DQ0–

DQ7. The Am29F080 is offered in a 40-pin TSOP, or

44-pin PSOP package. This device is designed to be

programmed in-system with the standard system

The standard Am29F080 offers access times of 85 ns,

90 ns, 120 ns, and 150 ns allowing operation of high-

speed microprocessors without wait states. To

eliminate bus contention the device has separate chip

enable (CE), write enable (WE), and output enable

(OE) controls.

The Am29F080 is entirely command set compatible

with the JEDEC single-power-supply Flash standard.

Commands are written to the command register using

standard microprocessor write timings. Register

contents serve as input to an internal state-machine

which controls the erase and programming circuitry.

Write cycles also internally latch addresses and data

5.0 volt V

supply. 12.0 volt V is not required for

program or erase operations. The device can also be

reprogrammed in standard EPROM programmers.
