General Description

The USB2226 is a USB 2.0 Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF and CF Ultra I/II) in True IDE Mode only, SmartMedia (SM) and XD cards, Memory Stick (MS), Memory Stick DUO (MSDUO) and Memory Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard (MMC) flash memory devices. It provides a single chip solution for the most popular flash memory cards in the market.

The device consists of a USB 2.0 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. SM controller supports both SM and xD cards.

The USB2226 can read and write the following card formats:

	Secure Digital (SD), High Capacity SD (HC-SD), High Speed SD (HS-SD), Mini-SD, Micro-SD
	MultiMediaCard (MMC), MMCplus (HS-MMC), High Capacity MMC (HC-MMC), RS-MMC, MMCMobile
	Memory Stick (MS), MS Duo, Memory Stick PRO (MSPro), Memory Stick PRO-HG (Pro-HG)
	xD Picture Card, Type M, Type H
	SmartMedia (SM), TransFlash
	Compact Flash
	MicroDrive

Media activity LED output is also provided.

Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro cards.

The internal ROM program implements a multi-LUN CF/SD/MMC/SM/MS reader function 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.
