描述 Description

The GL827S 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 Plus, MMC Micro, 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 PRO-HGTM (MS PRO-HG), Memory Stick ROM, MS PRO Micro, and xD-Picture CardTM (xD) on one chip. As a single chip solution for USB 2.0 flash card reader, the GL827S complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and flash card interface specification each.\r
\r
The GL827S can support different kinds of interfaces in single slot and integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces.\r
\r
The GL827S pin assignment design fits to card sockets to provide easier PCB layout. 48 Pin LQFP (7mm x 7mm) , QFN28 (5mm x 5mm) and QFN24 (4mm x 4mm) are available package types.
