1. Description

The AT45DCB008D, AT45DCB004D and AT45DCB002D are 2.7-volt only SPI com-

patible serial interface DataFlash^®Cards. They are offered in 8-megabyte (64-Mbit),

4-megabyte (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.
