MCHPUSB3320C-EZK
Overview
The USB3320C-EZK is a high-speed USB 2.0 physical layer transceiver (PHY) that utilizes a ULPI interface to connect to a link layer or MCU. It features Microchip's flexPWR technology to reduce power consumption and supports a wide supply voltage range from 1.8V to 3.3V. This transceiver includes integrated ESD protection, an over-voltage protection circuit, and supports USB On-The-Go (OTG) protocols.
Why Choose This Part
This transceiver offers high design flexibility with selectable reference clock frequencies and a small 5x5mm QFN-32 footprint. It reduces BOM cost and complexity by integrating an internal oscillator, USB switch, and comprehensive protection circuitry including OVP and ESD suppression. The low latency receiver and 30uA sleep current make it suitable for power-sensitive high-speed applications.
Applications
Key Specifications
Getting Started
Designers should ensure the ULPI interface timing is tightly matched in PCB layout between the USB3320 and the host controller. Evaluation can be performed using Microchip's USB3320 evaluation boards or by interfacing with FPGA development kits that feature a ULPI expansion header. Configuration is typically handled via the ULPI register set to manage power modes and OTG features.
