Notes
2. Pins are No Connect (NC) on devices without USB. NC means that the pin has no electrical connection. The pin can be left floating or tied to a supply voltage or ground.
3. The center pad on the QFN package should be connected to digital ground (Vssd) for best mechanical, thermal, and electrical performance. If not connected to
ground, it should be electrically floated and not connected to any other signal.
