GENERAL DESCRIPTION

The Am29LV002 is a 2 Mbit, 3.0 Volt-only Flash memory organized as 262,144 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7–DQ0. All read, program, and erase operations are accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS

■ 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)

— Automatic Sleep Mode: 200 nA

— Standby mode: 200 nA

— Read mode: 10 mA

— Program/erase mode: 20 mA

■ Flexible sector architecture

— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and three 64 Kbyte sectors

— Supports control code and data storage on a single device

— Sector Protection features:

A hardware method of locking a sector to prevent any program or erase operations within that sector

Temporary Sector Unprotect feature allows code changes in previously locked sectors

■ Top or bottom boot block configurations available

■ Embedded Algorithms

— Embedded Erase algorithms automatically preprogram and erase the entire chip or any combination of designated sectors

— Embedded Program algorithms automatically write and verify bytes or words 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 single power 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 feature

— 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 the read mode
