AM29F040B-55JF PLCC32 FLASH 4M (512Kx8) 55ns 5V Parallel NOR

 

4 Megabit (512 K x 8-Bit) CMOS 5.0 Volt-only, Uniform Sector Flash Memory

Embedded Erase algorithm automatically preprograms and erases the entire chip or any 

combination of designated sectors  Embedded Program algorithm automatically 

writes and verifies bytes at specified addresses 

• Minimum 1,000,000 program/erase cycles per sector guaranteed

• 20-year data retention at 125°C — Reliable operation for the life of the system

• Package options — 32-pin PLCC or TSOP

• Compatible with JEDEC standards — Pinout and software compatible with 

single-power-supply Flash standard — Superior inadvertent write protection

• Data# Polling and toggle bits — Provides a software method of detecting 

program or erase cycle completion

• Erase Suspend/Erase Resume — Suspends a sector erase operation to read data 

from, or program data to, a non-erasing sector,  then resumes the erase operation

 

• 5.0 V ± 10% for read and write operations

— Minimizes system level power requirements

• Manufactured on 0.32 µm process technology

— Compatible with 0.5 µm Am29F040 device

• High performance

— Access times as fast as 55 ns

• Low power consumption

— 20 mA typical active read current

— 30 mA typical program/erase current

— 1 µA typical standby current (standard access 

time to active mode)

• Flexible sector architecture

— 8 uniform sectors of 64 Kbytes each

— Any combination of sectors can be erased

— Supports full chip erase

— Sector protection:

A hardware method of locking sectors to prevent 

 

any program or erase operations within that sector
