Description

7-pin card is 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 AT45DB321C DataFlash

datasheet.
