Reduced Size MultiMediaCards (RS-MMCTM)
Posted by Jason Dunn in "NEWS" @ 12:00 PM
So am I the only one who thought that MultiMediaCards were small enough already? Apparently the people behing MMC didn't think so - they've released a new form of MMC that's 40% smaller than before. They have the same 7-pin connector as before, so they're compatible with current devices...although I have to admit I'm confused how this will work since the cards are now 18mm tall instead of 32mm tall, which begs the question of how we'll get them in and out of our Pocket PCs. An adaptor of some sort?
Volume (in cm3 ):Device type
5.14: CompactFlash
3.01: Sony Memory Stick
1.27: Smart Media
1.08: MultiMediaCard (Standard)
0.85: xD-Picture Card
0.60: MultiMediaCard (RS-MMC)
"A reduced-size standard for the MultiMediaCard™ was approved at the MultiMediaCard Association’s recent membership meeting in Boston, according to Andy Prophet, Executive Director of the trade organization.
The new Reduced Size MultiMediaCards (RS-MMCTM) will store data for mobile phones in a form factor that is approximately one-half the size of the standard MultiMediaCard. The new cards will be manufactured and marketed by various members of the MMCA with density ranges of 16/32/64 Mbytes available immediately, expanding to 128 and 256 Mbytes later in 2003. Both standard and RS-MMCs have seven pins and can be used in existing host platform. However, the MMCA believes the new RS-MMCs will find most acceptance in next-generation smart mobile phones. The RS-MMC proposal was cosponsored by Hitachi Ltd. and EEMS Italia SpA, Europe's leading provider of back-end manufacturing services for semiconductor memory.
Dimensions of the reduced size cards are 24x18x1.4 mm3, reduced from 24x32x1.4 mm³ in existing cards. The reduced size cards are supported by cell phone makers that understand the advantage for their next generation products where space and power are at a premium. In addition, compliance issues have been taken into consideration so that, for example, a card from a cell phone can be inserted in a digital camera."
