Description
General part information
USB4640 Series
Microchip's USB4640 is the world's first Hi-Speed Inter-Chip (HSIC) enabled USB 2.0 hub and Flash media card reader combo solution. The 480Mbps, 2-pin HSIC 1.O-compliant upstream port provides an ultra-fast interface between an HSIC-enabled host and today's most popular Flash media cards as well as a versatile, cost-effective and power-efficient USB 2.0 hub controller with two downstream ports for Hi-Speed/Full-Speed/Low-Speed USB port expansion. HSIC's digital interconnect bus bypasses the traditional USB analog PHY, reducing power consumption while maintaining transparency to the USB drivers and software.
The USB4640 serves as a fully-integrated, single-chip solution combining USB hub expansion with ultra high-performance Flash card media reader/writer capabilities. Average sustained Flash media transfer rates exceeding 35 MB/s\* are possible if the media and host can support those rates. The Flash media controller allows read/write capability to Flash media formats from the following families: xD-Picture Card™ (xD); Memory Stick® (MS); Secure Digital (SD); MultiMediaCard™ (MMC).
