Introduction

AI Translation

The GL823 is a USB 2.0 SD/MMC Flash Card Reader single chip. It supports USB 2.0 high-speed transmission to Secure Digital (SD), SDHC, SDXC, miniSD, microSD (T-Flash), MultiMediaCard (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.
