USB2240/USB2241
Ultra Fast USB 2.0 Multi-Format
Flash Media Controller
PRODUCT FEATURES
Datasheet
General Description
The SMSC USB2240/USB2241 is a USB 2.0 compliant, high
speed Mass Storage Class Peripheral Controller intended for
reading and writing to more than 20 popular flash media
formats from the xD Picture CardTM (xD)1, Memory StickTM
(MS), Secure Digital (SD), and MultiMediaCardTM (MMC)
families.
The SMSC USB2240/USB2241 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
36-pin QFN lead-free RoHS compliant package
Targeted for applications in which single or "combo"
media sockets are used
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 multiplexed
interface for use with “combo” card sockets
