USB2640数据手册集成电路（IC）的专用规格书PDF

描述 Description

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/MMC/eMMC 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.**
