Description

The AT45DCB008, AT45DCB004 and AT45DCB002 are 2.7-volt only SPI compatible

serial interface DataFlash

® Cards. They are offered in 8-megabyte (64-Mbit), 4-mega-

byte (32-Mbit) and 2-megabyte (16-Mbit) densities. These 7-pin cards are form factor

compatible to the MultiMediaCard standard leveraging on a wide range of low cost

connectors that are commercially available. Additionally, the DataFlash Card is pinout

compatible to the SPI version of the MMC card.

The small form factor and simple interface make the DataFlash Card ideal for a wide

variety of data- and program code-storage applications where a removable storage

medium is required. Applications range from voice/audio, text or image storage to

software applications, system upgrades and software patches.

For detailed device specifications, please refer to the corresponding DataFlash

datasheets:

• AT45DCB008 reference AT45DB642

• AT45DCB004 reference AT45DB321B

• AT45DCB002 reference AT45DB161B
