5th Generation Hi-Speed USB Flash Media and IrDA Controller with Integrated Card Power FETs
Revision 1.3 (02-13-06)
SMSC USB2229/USB2230
Chapter 1 General Description
The USB2229/USB2230 is a Hi-Speed USB IrDA and Bulk Only Mass Storage Class Peripheral
Controller. The Bulk Only Mass Storage Class Peripheral Controller supports CompactFlash (CF) in
True IDE Mode only, SmartMedia (SM), Memory Stick (MS) including both serial and parallel interface
and Secure Digital/MultiMediaCard (SD/MMC) flash memory devices. It provides a single chip solution
for the most popular flash memory cards in the market. In addition, the IrDA controller consists of the
SMSC IrCC block, which includes a Synchronous Communications Engine (SCE).
The IrCC SCE supports FIR and SIR IrDA. The IrCC offers flexible signal routing and programmable
output control through the Raw mode interface, General Purpose Data pins and Output Multiplexer.
Chip-level address decoding is required to access the IrCC register set.
The device consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded
scratchpad, and program SRAM, and IrDA, CF, MS, SM and SD controllers. The SD controller supports
both SD and MMC devices.
Provisions for external Flash Memory up to 128K bytes for program storage is provided (note: when
Bank switching is enabled the upper 64K will map into the 8051 ROM space, otherwise, only the first
64K bytes is used).
12K bytes of scratchpad SRAM and 768Bytes of program SRAM are also provided.
Twelve 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
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.
