USB82642

The USB82642 offers a versatile, cost-effective and energy-efficient hub controller with 2 downstream USB2.0 ports and a Secure Digital/Memory Stick flash media interface. The flash media interface can support sustained transfer rates exceeding 35 MB/s, if the flash media, SDIO client and host support those rates. The USB82642 is designed for applications that demand low power and a small footprint without compromising performance. Offering a high level of interoperability, the USB82642 allows system designers the flexibility of independent access to a wide selection of flash media and additional downstream USB access ports.

The USB82642 consists of USB 2.0 device transceivers with 2-port hub functionality, a fast 8051 microprocessor with Secure Digital/Memory Stick interfaces in a single, fully-integrated chip. It offers USB expansion as well as a flash media read/write interface capable of ultra high performance operation. Various programmable features, including Microchip's unique PortMap, PortSwap and PHYBoost, are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost.
