Am29F002B/Am29F002NB

2 Megabit (256 K x 8-Bit)

CMOS 5.0 Volt-only Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

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

program operations

— Minimizes system level requirements

■ Manufactured on 0.32 µm process technology

— Compatible with 0.5 µm Am29F002 device

■ 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 1,000,000 write cycle guarantee per

sector

■ 20-year data retention at 125

°C

— Reliable operation for the life of the system

■ Package option

— 32-pin PDIP

— 32-pin TSOP

— 32-pin PLCC

■ 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

■ 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 Am29F002NB)
