GL823K Product details

DESCRIPTION
The GL823K is a USB 2.0 Single-LUN card reader controller which can support SD/MMC/MSPRO Flash
Memory Cards. It supports USB 2.0 high-speed transmission to Secure Digital
TM
(SD), SDHC, SDXC,
miniSDTM, microSDTM(T-Flash), MultiMediaCard
TM
(MMC), RS MultiMediaCardTM (RS MMC), MMCmicro ,
HS-MMC, MMCmobile, Memory Stick PROTM (MS PRO), Memory Stick PROTM Duo (MS PRO Duo),
Memory Stick PRO-HGTM (MS PRO-HG), MS Micro (M2) on one chip. As a single chip solution for USB 2.0
flash card reader, the GL823K complies with Universal Serial Bus specification rev. 2.0, USB Storage Class
Specification ver.1.0, and each flash card interface specification.
The GL823K 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 regulator, 3.3V to 1.8V regulator 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.
The GL823K implements USB disconnect function; it can be used for Mobile cable/ OTG reader/ PC card reader
application
