If your host processor runs its ULPI port at 1.8V, the USB3318-CP accepts that rail directly — no extra regulator or level shifter needed. The 24-QFN (4x4 mm) with exposed pad requires a solder-paste stencil aperture that covers at least 50% of the pad area for reliable solder joint formation. The centre pad must be connected to the PCB ground plane with multiple vias to dissipate heat from the transceiver's internal PHY.","metaTitle":"USB3318-CP USB 2.0 ULPI Transceiver – Microchip flexPWR™","metaDescription":"USB3318-CP: USB 2.0 ULPI transceiver from Microchip flexPWR™ series. 1.8V–3.6V supply, -40°C to 85°C, 24-QFN.
