MultiMediaCard: Flash memory memory card standard. Unveiled in 1997 by Siemens AG and SanDisk. Free documentation as opposed to SD-Card standard. Which sandisk.com doesn't follow anywayTemplate:Fact.

Local projects

Many projects at OpenCircuits use the MMC protocol to talk to a flash memory card (even when that card is actually a SD card). These include the Minimig Project and many of the Music Player projects.

  • the TRAXMOD shows how a ARM can play raw digital audio files streaming off of a FAT formatted MMC/SD Card.
  • MMC Card Reader for the dsPic33F
