1. Description
The AT45DCB004C is 2.7-volt SPI compatible serial interface DataFlash^® Card. This
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.
