It sits in the signal path between a low-voltage SoC or FPGA and the USB connector, handling the level translation and line-state negotiation for full-speed and high-speed signalling. The 1.62V–1.98V supply range means this part runs directly off a 1.8V rail without an external LDO — useful when the main processor already uses that voltage. The industrial temperature grade (-40°C to 85°C) covers outdoor telecom cabinets, factory-floor controllers, and automotive cabin-zone modules that are not AEC-Q100 graded. ## Package and supply considerations Housed in a 24-VFQFN with exposed pad (4x4 mm body), the USB3319C-CP-TR requires a thermal land on the PCB to pull heat from the die. The pad must be connected to ground (GND) and stitched with vias to the inner-layer plane — skipping that step raises the junction temperature above the 85°C limit in a warm enclosure. The supply voltage tolerance is tight: 1.62V minimum, 1.98V maximum. A 1.8V rail with ±5% regulation stays inside that window, but a rail that droops below 1.62V during USB resume or high-current bursts will cause the transceiver to lose lock. Budget the IR drop from the regulator to the QFN pad. ## Active lifecycle and sourcing Microchip lists the USB3319C-CP-TR as Active and ROHS3 compliant.","metaTitle":"USB3319C-CP-TR USB 2.0 Transceiver flexPWR™ 24-QFN","metaDescription":"Microchip USB3319C-CP-TR USB 2.0 transceiver, flexPWR™ series, 1.62V–1.98V supply, -40°C to 85°C, 24-VFQFN.

The difference is packaging: USB3319C-CP-TR is supplied in Tape & Reel (TR), while USB3319C-CP is in Cut Tape (CT). The TR variant is intended for automated pick-and-place assembly lines; CT is for smaller quantities and hand assembly.

The transceiver's I/O levels are referenced to that supply, so it interfaces directly with 1.8V-logic processors without additional level shifters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/USB3319C-CP-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/USB3319C-CP-TR when reusing this data.
