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
