MICROCHIP USB3340-EZK

The USB3340 is a Hi-Speed USB 2.0 transceiver providing a physical layer (PHY) solution for portable electronic devices, supporting both commercial and industrial temperature applications. Multiple advanced features reduce eBOM component count and PCB area. Excellent ESD robustness eliminates the need for external ESD protection devices in typical applications. An internal overvoltage protection circuit (OVP) protects the USB3340's VBUS pin against voltages up to 30V. By utilizing a reference clock from the link, the USB3340 eliminates the need for a dedicated crystal reference in the design, reducing cost. The USB3340 integrates 3.3V and 1.8V regulators, enabling operation from a single power supply. The device is optimized for portable applications where low operating and standby current are critical.
