USB3318C-CP-TR

Product Overview

The Microchip Technology USB3318C-CP-TR is a half-duplex USB 2.0 transceiver intended for surface-mount printed circuit board assembly. It is an interface transceiver for USB 2.0 signaling. It is housed in a 24-VQFN exposed-pad package with a 4 mm x 4 mm body. The device operates from a 1.8 V to 3.3 V supply and is specified for an operating temperature range of -40°C to 85°C. The USB 2.0 receiver path has a 150 mV receiver hysteresis.

Design & Procurement Notes

Design review should confirm that the system uses USB 2.0 half-duplex operation and that the available supply falls within 1.8 V to 3.3 V. Board layout must accommodate the 24-QFN (4x4) exposed-pad surface-mount package. Because the device is half-duplex, system architecture should account for single-direction data flow at a time. The 150 mV receiver hysteresis and -40°C to 85°C operating temperature range should be checked against signal-integrity and environmental requirements. Procurement should verify the exact part number USB3318C-CP-TR and the 24-VQFN package variant. The supply range, temperature range, package size, and exact part number should be included in the design documentation.
