The GL822 is a USB 2.0 SD 3.0 UHS-I Memory Card Reader single chip. It supports USB 2.0 high-speed transmission to Secure DigitalTM (SD), SDHC, miniSD, microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro, MMCmobile, 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) and MS PRO Micro on one chip. It also supports next generation huge density memory cards (up to 2TB), such as SDXC and Memory Stick XC. As a single chip solution for USB 2.0 flash card reader, the GL822 complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and SD/MMC card interface specification.\r\n\r\n The GL822 integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its’ pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 5V to 3.3V and 3.3V to 1.8V regulators and power MOSFETs and it enables the function of on-chip clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.
