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 USB2232 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.

USB2232 is provided for indicators, external serial EEPROM for OEM ID and system configuration information, and other special functions.
