GENERALDESCRIPTION
The GL816is a highly integrated, flexible application USB   2.0 Multi-Interface Flash  Card Reader controller. It supports USB 2.0 high-speed transmission to  PCMCIA,  CompactFlash (CF),  Micro Drive, SmartMedia(SM), Secure Digital(SD), Multi Media Card (MMC),   and  MemoryStick (MS) interface on one chip. Besides the flash card interface controller each, the GL816integrates Genesys Logic own design USB 2.0high-speed  UTMI  (USB 2.0  Transceiver  Macrocell  I nterface)  transceiver. As a single chip solution for USB 2.0 multi flash card reader, the GL816complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and flash card interface specification each.
