描述：GL823A-06 电子元器件 GENESYS/创惟科技 封装QFN-24A USB 2.0 SD/MMC读卡器单芯片

GENERAL DESCRIPTION
The GL823 is a USB 2.0 SD/MMC Flash Card Reader single chip. It supports USB 2.0 high-speed transmission
to Secure DigitalTM (SD), SDHC, SDXC, miniSD, microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC,
MMCmicro, MMCmobile on one chip. As a single chip solution for USB 2.0 flash card reader, the GL823
complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and
SD/MMC card interface specification.
The GL823 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.
