USB224x

Ultra Fast USB 2.0 Multi-Format, SD/MMC,

and MS Flash Media Controllers

PRODUCT FEATURES

General Description

The SMSC USB224x is a USB 2.0 compliant, Hi-Speed

bulk only

mass storage class peripheral controller intended

for reading and writing to popular flash media from the xD-

Picture Card

(xD)

, Memory Stick

(MS), Secure Digital

(SD), and MultiMediaCard

(MMC) families.

The SMSC USB224x is a fully integrated, single chip

solution capable of ultra high performance operation.

Average sustained transfer rates exceeding 35 MB/s are

possible if the media and host can support those rates. The

USB2244/44i includes provisions to read/write secure

media formats.


