Chapter 1
General Description
The USB2224 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) and XD cards, 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.
