Chapter 1
General Description
The USB2223-03 is a USB2.0 Bulk Only Mass Storage Class Peripheral Controller intended for supporting
CompactFlash (CF and CF Ultra I/II) in True IDE Mode only, SmartMedia (SM), Memory Stick (MS),
Memory Stick DUO (MSDUO) and Memory Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard
(MMC) flash memory devices. It provides a single chip solution for the most popular flash memory cards in
the market.
The device consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded
scratchpad, and program SRAM, and CF, MS, SM and SD controllers. The SD controller supports both SD
and MMC devices.
Provisions for external Flash Memory up to 64K bytes for program storage is provided.
12K bytes of scratchpad SRAM and 768 Bytes of program SRAM are also provided.
Fifteen GPIO pins are provided for indicators, external serial EEPROM for OEM id and system
configuration information, and other special functions.
The internal ROM program is capable of implementing any combination of single or multi-LUN
CF/SD/MMC/SM/MS reader functions with individual card power control and activity indication. SMSC also
provides licenses** for Win98 and Win2K drivers and setup utilities. Note: Please check with SMSC for
precise features and capabilities for the current ROM code release.
