MultiMediaCardTM
1 Introduction to the MultiMediaCard
The MultiMediaCard is a universal low cost data storage and communication media. It is designed to
cover a wide area of applications as cellula phone, electronic toys, organizers, PDAs, cameras, smart
phones, digital recorders, MP3 players, pagers, etc. Targeted features are high mobility and high
performance at a low cost price. It might also be expressed in terms of low power consumption and
high data throughput at the memory card interface
The MultiMediaCard communication is based on an advanced 7-pin serial bus designed to operate in a
low voltage range. The communication protocol is defined as a part of this standard and referred to as
MultiMediaCard mode. For compatibility to existing controllers the cards may offer, in addition to the
MultiMediaCard mode, an alternate communication protocol which is based on the SPI standard
