USB2640i/USB2641i

Industrial Temperature USB 2.0

Flash Media Controller and

USB Hub Combo

PRODUCT FEATURES

General Description

The SMSC USB2640i/USB2641i is a USB 2.0 compliant, Hi-

Speed hub for USB port expansion with an attached mass

storage class peripheral controller. The controller allows

read/write capability to popular flash media formats from the

following families:

xD-Picture Card

(xD)

Memory Stick

(MS)

Secure Digital

(SD)

MultiMediaCard

(MMC)

The USB2640i/USB2641i is a fully integrated, single chip

solution providing USB expansion and integrated flash card

media reader/writer capability of ultra high performance

operation. Average sustained transfer rates exceeding 35 MB/s

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

Datasheet

Features
