GENERAL DESCRIPTION

The GL827 is USB 2.0 Single Interface Flash Card Reader controller. It supports USB 2.0 high-speed transmission to Secure DigitalTM (SD), SDHC, Mini SDTM, Micro SDTM , T-Flash , MultiMediaCardTM (MMC), RS MultiMediaCardTM (RS MMC), MMC Micro , HS-MMC, MMC-Mobile , Memory StickTM (MS), Memory Stick DuoTM (MS Duo), High Speed Memory StickTM (HS MS), Memory Stick PROTM (MS PRO), Memory Stick PROTM Duo (MS PRO Duo), Memory Stick ROM, MS PRO Micro, SmartMediaTM (SM) , and xD-Picture Card TM (xD) on one chip. As a single chip solution for USB 2.0 flash card reader, the GL827 complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and flash card interface specification each.
The GL827 can support different kinds of interfaces in single slot. For the best performance consideration, the GL827 integrates high efficiency card interface hardware engine for data transfer. The GL827 also supports firmware upgrade via USB interface (100 Pin LQFP), and external flash read/ write for firmware upgrade and other applications.
The GL827 pin assignment design fits to card sockets to provide easier PCB layout. 100 Pin LQFP (14mmx14mm), 48 Pin LQFP/LQFN (7mm x 7mm), QFN24 (4mm x 4mm), SSOP28 (150mil) are available package types.
