PRODUCT FEATURES

USB2250/51/59

Ultra Fast USB 2.0 Multi-Format

Flash Media Controller

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® (CF), SmartMediaTM (SM),

xD Picture CardTM (xD)1, Memory StickTM (MS), Secure

Digital (SD), and MultiMediaCardTM (MMC) families.

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.

General Features

128-pin VTQFP lead-free RoHS compliant package

Targeted for applications in which single or "combo"

media sockets are used. Supports multiple simultaneous

card insertions

Flexible assignment of number of LUNs and how card

types are associated with the LUNs

Hardware-controlled data flow architecture for all self-

mapped media

Pipelined hardware support for access to non-self-

mapped media

Hardware Features

Single Chip Flash Media Controller with non-multiplexed

interface for independent card sockets
