Device Overview

Summary

The USB2642 is a USB 2.0 compliant, hi-speed huband card reader combo solution. This fully-integrated, single chip solution provides USB expansion and flash media reader/writer integration. 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 DigitalTM (SD)
• SD High CapacityTM (SDHC)
• SD Extended CapacityTM (SDXC)
• MultiMediaCardTM (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 I2CTM 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 SDIO cards.
