PRODUCT FEATURES
USB224x
Ultra Fast USB 2.0 Multi-
Format, SD/MMC, and MS
Flash Media Controllers
General Description
The SMSC USB224x is a USB 2.0 compliant, Hi-Speed
bulk only1 mass storage class peripheral controller intended
for reading and writing to popular flash media from the xD-
Picture CardTM (xD)2, Memory Stick (MS), Secure Digital
(SD), and MultiMediaCardTM (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.
