The uMMC is quite possibly the easiest SD card interface for a microcontroller. With a time-tested reliable file system engine, the uMMC bridges the gap between PCs and microcontrollers by providing an easy way of accessing data from SD cards.
Using the serial interface on the uMMC, you can read from and write data to SD cards in FAT12, FAT16, and FAT32 format -- virtually any card available from 1MB up to 32GB and beyond.
Firmware can be updated, as new features become available, through the serial interface.
SD/MMC card not included.
