USB 2.0 transceiver for low-voltage portable and industrial ports
The USB3317C-CP-TR is a USB 2.0 transceiver from Microchip's flexPWR™ series, designed to bridge a host controller or processor to a USB 2.0 bus. Its supply range of 1.6V to 3.6V lets it run directly off a 1.8V, 2.5V, or 3.3V rail — no extra regulator needed for the I/O interface. The -40°C to 85°C operating temperature covers industrial and outdoor applications where a commercial-grade part would be marginal.
Supply voltage and temperature grade — what they mean for the BOM
The 1.6V minimum supply is the key differentiator from older USB transceivers that require 3.0V or higher. If your processor core runs at 1.8V, this part eliminates a level shifter and a second regulator. The industrial temperature range (-40°C to 85°C) is specified across the full supply window — not just at 3.3V — so the transceiver stays within USB 2.0 signal-level specs when the board is cold-soaked or under a heat lamp.
Active production — no obsolescence risk for new builds
The USB3317C-CP-TR carries an Active product status with ROHS3 compliance. For volume BOM commitments, the part is sourced per RFQ — no last-time-buy window to chase.
Package and footprint — 24-QFN with exposed pad
The 24-VFQFN exposed-pad package (4x4 mm body) requires a thermal land on the PCB to sink heat from the die and to provide a low-inductance ground return for the USB high-speed signals. The supplier device package is 24-QFN-EP. Tape & Reel and Cut Tape options are available for prototyping or production reels.
