Overview

The USB3320C-EZK-TR is a high-speed USB 2.0 Physical Layer Transceiver (PHY) that utilizes a ULPI interface to connect to Link Layer controllers. It features Microchip's flexPWR technology to minimize power consumption while providing integrated 3.3V regulators and over-voltage protection. This transceiver is designed to support USB Host, Device, and OTG roles in a compact 32-pin QFN package.

Why Choose This Part

The USB3320C excels due to its wrapper-less design and flexPWR technology, which reduces the external Bill of Materials (BOM) by integrating a 3.3V regulator and ESD protection. It offers flexible clocking options, supporting both internal oscillators and external reference clocks, while maintaining a low synchronous run current of 7.5mA.

Applications

Industrial Embedded Hosts
Adding USB 2.0 high-speed connectivity to FPGAs or microcontrollers that lack an integrated PHY but provide a ULPI interface.
Portable Media Players
Leveraging the integrated battery-to-3.3V regulator and low 18uA standby current for battery-powered consumer devices.
USB OTG Peripherals
Supporting dual-role applications that require Host Negotiation Protocol (HNP) and Session Request Protocol (SRP) capabilities.
Interface Bridging
Utilizing the integrated UART and Headset Audio modes to multiplex different signal types over a standard USB Type-A or Micro-AB connector.

Getting Started

Implementation requires a ULPI-compliant Link Layer controller, typically found in high-end MCUs or FPGAs. Engineers should ensure the 5x5mm QFN package thermal pad is properly grounded and consult the Microchip USB3320 evaluation board schematics for reference layout patterns. Software integration is usually handled via the USB stack provided by the FPGA vendor or RTOS ecosystem.
