SMSC USB2231/USB2232
DATASHEET
Chapter 1 General Description
The USB2231/USB2232 is a Hi-Speed USB Consumer IR 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 CIR controller consists
of the SMSC CIrCC block, which includes a Synchronous Communications Engine (SCE) and
hardware demodulators for the supported CIR formats.
The device consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded
scratchpad, and program SRAM, and CIR, 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
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.
