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

DATE CODED 9846

The Am29F040B is a 4 Mbit, 5.0 volt-only Flash memory organized as 524,288 Kbytes of 8 bits each. The
512 Kbytes of data are divided into eight sectors of 64
Kbytes each for flexible erase capability. The 8 bits of
data appear on DQ0–DQ7.

DISTINCTIVE CHARACTERISTICS
■ 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
■ 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 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 — 32-pin PDIP
■ 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

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large ‘Milspec’ Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, stored with us still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.
