USB2640
Microchip's USB264x/2660 family combines an ultra-fast interface between a USB host and today's most popular Flash media cards with a versatile, cost-effective and power-efficient 2-port Hi-Speed USB 2.0 hub controller. USB264x/2660 is designed for applications that demand low power, small footprint and reduced BOM without compromising performance or features.
Offering a high level of USB 2.0 compliance and interoperability, the USB264x/2660 family allows system designers the flexibility of independent access to a wide selection of Flash media readers and also provides additional downstream USB access ports.
Each device in the USB264x/2660 family consists of USB 2.0 device transceivers with 2-port hub functionality, a fast 8051 microprocessor and Memory Stick® (MS), xD-Picture Card™* (xD) and Secure Digital (SD) controllers in a single, fully-integrated chip. The USB2660 has an additional SD/SDIO port. This family of devices offers USB expansion ports as well as a Flash card media reader/writer capable of ultra high-performance operation. Average sustained transfer rates exceeding 35MB/s are possible if the media and host can support those rates.**
*Microchip makes the following part-numbered device available for purchase only by customers who are xD-Picture Card licensees: USB2640, USB2660. By purchasing or ordering any of such devices, Buyer represents, warrants, and agrees that Buyer is a duly licensed Licensee under an xD-Picture CardTM License Agreement with Fuji Photo Film Co., Ltd., Olympus Optical Co., Ltd., and Toshiba Corporation; and that Buyer will maintain in effect such xD-Picture Card license and will give Microchip reasonable advance notice of any termination or expiration of such xD-Picture Card license, but in no event less than five days advance notice. Microchip may discontinue making such devices available for purchase by Buyer and/or discontinue further deliveries of such devices if such xD-Picture Card license shall expire, terminate, or cease to be in force, or if Buyer is or becomes in default of such xD-Picture Card license.
