General Description
The USB2227/USB2228 is a USB 2.0 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 USB 2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded
scratchpad, and program SRAM, and CF, MS, SM and SD controllers. The SD controller suppo rts both
SD and MMC devices. SM controller supports both SM and xD cards.
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.
Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro
cards.
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.
