GENERAL DESCRIPTION

The Am29F002 Family consists of 2 Mbit, 5.0 volt-only Flash memory devices organized as 262,144 bytes. The Am29F002 offers the RESET# function, the Am29F002N does not. The data appears on DQ7– DQ0. The device is offered in 32-pin PLCC, 32-pin TSOP, and 32-pin PDIP packages. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. No VPP is required for write or erase operations. The device can also be programmed in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

— 5.0 Volt-only operation for read, erase, and program operations

— Minimizes system level requirements

■ High performance

— Access times as fast as 55 ns

■ Low power consumption (typical values at 5 MHz)

— 1 μA standby mode current

— 20 mA read current

— 30 mA program/erase current

■ Flexible sector architecture

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

— Supports full chip erase

— Sector Protection features:

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

Sectors can be locked via programming equipment

Temporary Sector Unprotect feature allows code changes in previously locked sectors

■ Top or bottom boot block configurations available

■ 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

■ Minimum 100,000 write cycle guarantee per sector

■ Package option

— 32-pin PDIP

— 32-pin TSOP

— 32-pin PLCC

■ 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

■ 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 (not available on Am29F002N)
