1. Description
The AT45DCB008D, AT45DCB004D and AT45DCB002D 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.
