USB2660/USB2660i
Ultra Fast USB 2.0 Hub and
Multi-Format Flash Media
Controller with Dual SD
Interfaces
PRODUCT FEATURES
General Description
The SMSC USB2660/USB2660i is a USB 2.0 compliant, Hi-
Speed hub, card reader, and protocol converter combo
solution. This fully integrated single chip solution provides USB
expansion and flash card media reader/writer integration. SDIO
bridging is possible with custom firmware. The SMSC
USB2660/USB2660i provides an ultra fast interface between a
USB host and today’s popular flash media formats. The
controller allows read/write capability to flash media from the
following families:

Highlights
2 exposed Hi-Speed USB 2.0 downstream ports for external
peripheral expansion
The dedicated flash media reader is internally attached to a
3rd downstream port of the hub as a USB Compound
Device
— a single or multiplexed flash media reader interface
— a non-multiplexed SD/SDIO interface (slot) for SD card reader
or SDIO bridging applications
Additional SD/SDIO port for card reader or to host wireless
applications such as WiFi
