USB3320

In Production

The USB3320 is a highly integrated full featured Hi-Speed USB 2.0 transceiver based on Microchip's proven ULPI interface. The USB3320 provides an extremely flexible solution in a convenient 5 x 5 mm QFN package. It supports a wide variety of different reference clock frequencies with one single part, as well as accepting clocking from crystal/resonators and the ULPI 60Mhz Clock-In mode. As with previous generations of Microchip's USB transceivers, the USB3320 integrates a USB switch and both ESD and VBUS over-voltage protection devices.Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects.
