SMSC USB2250/51/59

PRODUCT FEATURES

General Description

The SMSC USB2250/51/59 is a USB 2.0 compliant, high

speed Mass Storage Class Peripheral Controller intended for

reading and writing to more than 24 popular flash media

formats from the CompactFlash

xD Picture Card

Digital (SD), and MultiMediaCard

The SMSC USB2250/51/59 is a fully integrated, single chip

solution capable of ultra high performance operation.

Average sustained transfer rates exceeding 35MB/s are

possible if the media and host can support those rates.
