General Description

The SMSC USB4640/USB4640i is a Hi-Speed HSIC

USB hub and card reader combo solution with an

upstream port compliant to HSIC 1.0, a supplement to

the USB 2.0 specification. The two downstream ports

are compliant with the USB 2.0 specification.

High Speed Inter-Chip (HSIC) is a digital interconnect

bus that enables the use of USB technology as a low-

power chip-to-chip interconnect at speeds up to 480

Mb/s. The HSIC interface is an industry standard 2-pin

digital interface which uses standard USB software. The

SMSC USB4640/USB4640i provides an ultra fast

interface between an HSIC enabled host and today’s

popular flash media formats. The controller allows

read/write capability to flash media from the following

families:

The USB4640/USB4640i offers a versatile, cost-

effective, and energy-efficient hub controller with 2

downstream USB 2.0 ports. This combo solution

leverages SMSC’s innovative technology that delivers

industry-leading data throughput in mixed-speed USB

environments. Average sustained transfer rates

exceeding 35 MB/s are possible
