The uMMC (µMMC or "micro MMC") is a small footprint data storage solution for rapid integration of FAT16 and FAT32 SD/MMC flash memory card storage. Now you can have all the convenience of the data storage from the popular flash cards available to your products.
Using the serial interface on the uMMC, you can read from and write data to SD/MMC cards in FAT16/FAT32 format, permitting access to any size of card commercially available (32MB to 2GB and beyond).
The serial interface is easy to use from both simple and advanced processors, so you can easily add large storage capacity to your next design.
You can organize your data into directories/folders as well as name the files how you wish. The card can be accessed by any other devices that support SD/MMC cards.
Firmware can be updated through the serial port.
