PRELIMINARY

Am29F400B

4 Megabit (512 K x 8-Bit/256 K x 16-Bit)

CMOS 5.0 Volt-only Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

■ Top or bottom boot block configurations

available

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

program operations

■ Embedded Algorithms

— Minimizes system level requirements

— Embedded Erase algorithm automatically

preprograms and erases the entire chip or any

combination of designated sectors

■ Manufactured on 0.35 µm process technology

— Compatible with 0.5 µm Am29F400 device

— Embedded Program algorithm automatically

writes and verifies data at specified addresses

■ High performance

— Access times as fast as 55 ns

■ Minimum 1,000,000 program/erase cycles per

■ Low power consumption (typical values at 5

sector guaranteed

MHz)

■ Package option

— 48-pin TSOP

— 44-pin SO

— 1 µA standby mode current

— 20 mA read current (byte mode)

— 28 mA read current (word mode)

— 30 mA program/erase current

■ Compatibility with JEDEC standards

— Pinout and software compatible with single-

power-supply Flash

■ Flexible sector architecture

— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and

seven 64 Kbyte sectors (byte mode)

— Superior inadvertent write protection

■ Data# Polling and toggle bits

— One 8 Kword, two 4 Kword, one 16 Kword, and

seven 32 Kword sectors (word mode)

— Provides a software method of detecting

program or erase operation completion

— Supports full chip erase

■ Ready/Busy# pin (RY/BY#)

— Sector Protection features:

— Provides a hardware method of detecting

program or erase cycle completion

A hardware method of locking a sector to

prevent any program or erase operations within

that sector

■ Erase Suspend/Erase Resume

Sectors can be locked via programming

equipment

— Suspends an erase operation to read data from,

or program data to, a sector that is not being

erased, then resumes the erase operation

Temporary Sector Unprotect feature allows code

changes in previously locked sectors

■ Hardware reset pin (RESET#)

— Hardware method to reset the device to reading

array data
