The Microchip USB2642 provides an ultra fast interface between a USB host and today’s popular flash media formats. The controller allows read/write capability to flash media including the following:

    • Secure Digital™ (SD)

    • SD High Capacity™ (SDHC)

    • SD Extended Capacity™ (SDXC)

    • MultiMediaCard™ (MMC)

    • Embedded MultiMediaCard (eMMC)

    The USB2642 offers a versatile, cost-effective and energy-efficient hub controller with 2 downstream USB 2.0 ports and a flash media interface. The flash media interface can support sustained transfer rates exceeding 35 MB/s. Additionally, the USB2642 provides an I²C over USB bridge and an SD over USB bridge. The I²C bridge allows for control of any I²C slave device operating at 50KHz serial clock, while the SD bridge supports the use of managing memory devices through SDIO commands.
