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)
