CHAPTER 1
GENERAL DESCRIPTION
The GL823K is a USB 2.0 Single-LUN card reader controller which can support SD/MMC/MSPRO Flash
TM
Memory Cards. It supports USB 2.0 high-speed transmission to Secure Digital
(SD), SDHC, SDXC,
TM
TM
TM
TM
miniSD , microSD (T-Flash), MultiMediaCard (MMC), RS MultiMediaCard (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.

4.1 OCCS USB PHY
The USB 2.0 Transceiver Macrocell is the analog circuitry that handles the low level USB protocol and signaling,
and shifts the clock domain of the data from the USB 2.0 rate to one that is compatible with the general logic. On
chip clock source and no need of 12MHz Crystal Clock input.
4.2 SIE
The Serial Interface Engine, which contains the USB PID and address recognition logic, and other sequencing
and state machine logic to handle USB packets and transactions.
4.3 EPFIFO
Endpoint FIFO includes Control FIFO (FIFO0) and Bulk In/Out FIFO
EP0 FIFO
FIFO of control endpoint 0. It is 64-byte FIFO and used for endpoint 0 data transfer.
Interrupt FIFO
64-byte depth FIFO of endpoint 3 for status interrupt
Bulk FIFO It can be in the TX mode or RX mode:
1. It contains ping-pong FIFO (512 bytes each bank) for transmit/receive data continuously.
2. It can be directly accessed by micro-controller
