MicroSD


MicroSD

microSD is a format for removable flash memory cards. It is derived from SanDisk TransFlash and is used mainly in mobile telephones, but also in handheld GPS devices, portable media players, digital audio players, expandable USB flash memory drives, and for Nintendo DS flashcards.

It is the smallest memory card available commercially, as of|2008|lc=on. At 15 mm × 11 mm × 1 mm (about the size of a fingernail), it is about a quarter the size of an SD card. [cite web|url=http://www.sdcard.org/developers/tech/microsd/ |title=microSD Card |publisher=SD Card Association |accessdate=2008-09-13] There are adapters which allow a microSD card to be used in devices intended for SD, miniSD, Memory Stick Duo and even USB cards. However, they are not universally compatible.

TransFlash and microSD cards are the same (each can be used in devices made for the other), except that microSD adds support for SDIO mode, enabling non-memory cards like Bluetooth, GPS, and Near Field Communication devices. [ [http://www.phonescoop.com/glossary/term.php?gid=179 microSD definition (Phone Scoop) ] ]

A point of confusion can come from the difference in the microSD and the newer micro SDHC format. The SD and SDHC share a same form factor, but not all devices are compatible with the newer high capacity format. This is even true with devices that have been developed by SanDisk such as their e200 series of MP3 players. Using 3rd party firmware however, SDHC reading capabilities can be possible, but requires an external writer

As of|2008|09, microSD cards are available in capacities from 64 MB to 16 GB.cite web|url=http://www.sandisk.com/Corporate/PressRoom/PressReleases/PressRelease.aspx?ID=4398|title=SANDISK ANNOUNCES WORLD’S LARGEST MOBILE PHONE MEMORY CARD CAPACITY WITH 16GB MICROSDHC AND M2|date=September 29, 2008|publisher=Sandisk] A 12 GB version was developed by SanDisk but never released.Fact|date=September 2008 Cards 4 GB and larger are only available in the newer SDHC format.

Manufacturer support

The microSD format is supported mainly by mobile phone manufacturers, among which Motorola was the first to adopt. Garmin makes GPS receivers with maps on microSD cards.

Most devices which support SD/miniSD can support microSD cards using an appropriate adapter (often sold with a microSD card), but support is not universal. SanDisk publishes a list of mobile phones with memory card support [http://www.sandisk.com/Assets/File/Compatibility/Mobile_Phones_with_Memory_Cards.pdf] (in PDF format). This gives the type of the memory card slot and lists the support for still-image cameras, video capture and music.

SanDisk's e200 series MP3 players support microSD card expansion, allowing additional storage of up to 2 GB. [http://usa.apacer.com/us/products/microSD_Card.htm] When using 3rd party firmware(rockbox), SDHC is supported.

RCA Pearl MP3 players (TH1100, TH1101 and TH1102) support the use of MicroSD cards for additional storage. [http://www.rcapearl.com/]
