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 USB2229 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 USB2229 consists of a USB 2.0 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.
