GENERAL DESCRIPTION

The Am29LV081 is an 8 Mbit, 3.0 volt-only Flash memory organized as 1,048,576 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7–DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device.

DISTINCTIVE CHARACTERISTICS

■ Optimized architecture for Miniature Card and

mass storage applications

■ Single power supply operation

— Full voltage range: 2.7 to 3.6 volt read and write

operations for battery-powered applications

— Regulated voltage range: 3.0 to 3.6 volt read and

write operations and for compatibility with high

performance 3.3 volt microprocessors

■ High performance

— Full voltage range: access times as fast as 100 ns

— Regulated voltage range: access times as fast

as 90 ns

■ Ultra low power consumption (typical values at 5 MHz)

— 200 nA Automatic Sleep mode current

— 200 nA standby mode current

— 10 mA read current

— 20 mA program/erase current

■ Flexible sector architecture

— Sixteen 64 Kbyte sectors

— Supports full chip erase

— Sector Protection features:

A hardware method of locking a sector (using

programming equipment) to prevent any

program or erase operations within that sector

Temporary Sector Unprotect feature 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 data at specified addresses

■ Typical 1,000,000 write cycles per sector

(100,000 cycles minimum guaranteed)

■ Package option

— 40-pin TSOP

■ Compatibility with JEDEC standards

— Pinout and software compatible with singlepower supply Flash

— Superior inadvertent write protection

■ Data# Polling and toggle bits

— Provides a software method of detecting

program or erase operation completion

■ Ready/Busy# pin (RY/BY#)

— Provides a hardware method of detecting

program or erase cycle completion

■ Erase Suspend/Erase Resume

— Suspends an erase operation to read data from,

or program data to, a sector that is not being

erased, then resumes the erase operation

■ Hardware reset pin (RESET#)

— Hardware method to reset the device to reading

array data
