MMCmobile has an extremely small form factor of 24mm x18mm x1.4mm, specifically designed to work best in mobile phones as it is space saving in size and uses a tiny amount of battery power.
MMCmobile is a dual voltage product, operating at both 1.65-1.95V and 2.7-3.6V ranges.
MMCmobile is fully backwards compatible with RSMMC (Reduced Size MultiMediaCard) and Dual Voltage RSMMC.

Operating at 52 MHz in x8bit mode, data can be transferred at up to 52MB/sec, (or 416 bits/sec). Along with its sister format MMCplus, this is the highest data transfer rate of all existing memory card standards available today.

With the use of an adaptor, which Integral supply with all MMCmobile cards, MMCmobile can be made full-size and work as a standard MultiMediaCard/MMCplus in many other devices such as digital cameras, MP3 players, navigation systems and PDA’s.
Your mobile phone will be able to store more images, ringtones, mp3s and movie clips then ever before.

Nokia handsets that are compatible with MMCmobile include the 6630, 6670, 6680, 6230i, 6681, 3230, N70, N90 and 770 Tablet
