ADVANCE INFORMATION

Am29SL400D

4 Megabit (512 K x 8-Bit/256 K x 16-Bit) CMOS 1.8 Volt-only Super

Low Voltage Flash Memory

DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

■ Unlock Bypass Program Command

— 1.65 to 1.95 V for read, program, and erase

operations

— Reduces overall programming time when

issuing multiple program command sequences

— Ideal for battery-powered applications

■ Manufactured on 0.23 µm process technology

■ High performance

■ Top or bottom boot block configurations

available

■ Minimum 1,000,000 erase cycle guarantee per

— Access times as fast as 90 ns

sector

■ Ultra low power consumption (typical values at

■ 20-year data retention at 125°C

5 MHz)

■ Package option

— 0.2 µA Automatic Sleep Mode current

— 0.2 µA standby mode current

— 5 mA read current

— 48-ball FBGA

■ Compatibility with JEDEC standards

— Pinout and software compatible with

single-power supply Flash

— 15 mA program/erase current

■ Flexible sector architecture

— Superior inadvertent write protection

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

seven 64 Kbyte sectors (byte mode)

■ Data# Polling and toggle bits

— Provides a software method of detecting

program or erase operation completion

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

seven 32 Kword sectors (word mode)

— 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

— Suspends an erase operation to read data from,

or program data to, a sector that is not being

erased, then resumes the erase operation

Sectors can be locked in-system or via

programming equipment

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
