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 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.
For volume BOM commitments, the part is sourced per RFQ — no last-time-buy window to chase.
