Description

The USB2223-03 is a USB2.0 Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF and CF Ultra I/II) in True IDE Mode only, SmartMedia (SM), Memory Stick (MS), Memory Stick DUO (MSDUO) and Memory Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard (MMC) flash memory devices. The USB2223-03 provides a single chip solution for the most popular flash memory cards in the market.

The USB2223-03 consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS, SM and SD controllers. The SD controller supports both SD and MMC devices.

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.

The USB2223-03 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.
