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-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.
