1. 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:
