Details
The SMSC USB4640/USB4640i is a Hi-Speed HSIC USB hub and card reader combo solution with an upstream port that is compliant to HSIC 1.0 (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 chipto-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 USB4640/USB4640i provides an ultra fast interface between an HSIC enabled
host and several popular flash media formats. The controller allows read/write capability to flash media from the following
families:
- Secure DigitalTM (SD)
- MultiMediaCardTM (MMC)
- Memory Stick® (MS)
- xD-Picture CardTM (xD)1
The USB4640/USB4640i 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 possible2.
