USB 2.0 half-duplex transceiver in a 24-QFN package
The USB3310C-CP-TR is a USB 2.0 half-duplex transceiver from Microchip's flexPWR™ series, integrating one driver and one receiver in a single 24-VFQFN exposed-pad package (4x4 mm). The 150 mV receiver hysteresis provides a noise margin on the USB DP/DM lines, helping maintain signal integrity in electrically noisy environments common in industrial and automotive applications.
Sourcing and lifecycle — active production, no obsolescence risk
This removes the single-source risk for BOM lines that depend on it. The part is ROHS3 compliant, meeting the current EU directive for lead-free soldering. Supplied in Tape & Reel (TR) or Cut Tape (CT) options, the TR variant is the standard production reel for automated pick-and-place assembly. The CT option suits prototype or low-volume builds.
Package and footprint — 24-QFN with exposed pad
The 24-VFQFN exposed-pad package measures 4x4 mm. The exposed pad also serves as a ground return for the USB interface; ensure the PCB land pattern matches the supplier device package drawing.
