MCHPUSB3320C
Overview
The USB3320C is a high-speed USB 2.0 transceiver (PHY) that utilizes a ULPI interface to bridge the physical USB layer with a Link Layer. It features Microchip's RapidCharge Anywhere technology for flexible battery charging support and operates with a very low standby current of approximately 18uA. This IC is designed to support High Speed (480 Mbps), Full Speed, and Low Speed USB communication while maintaining a small 32-pin QFN footprint.
Why Choose This Part
The device features a highly integrated design that includes a 5V tolerant I/O and an internal 3.3V regulator, reducing the overall bill of materials. It offers excellent power efficiency with an 18uA standby current and supports flexible clocking options via a 13MHz, 19.2MHz, 24MHz, or 26MHz reference. Its ability to switch into a UART mode provides additional design flexibility for debugging or legacy support.
Applications
Getting Started
To evaluate this transceiver, engineers typically interface it with an FPGA or MCU that features a ULPI-compliant MAC (Media Access Controller). Ensure the 32-pin QFN thermal pad is correctly soldered to the ground plane for optimal signal integrity and heat dissipation. Refer to the Microchip EVB-USB3320 evaluation board documentation for recommended layout patterns and decoupling capacitor placement.
