The Microchip USB flash media controller 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. It 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, it allows system designers the flexibility of independent access to a wide selection of flash media readers and also provides additional downstream USB access ports. The transaction translator (TT) in the hub supports operation of Full-Speed and Low-Speed peripherals.
