Notes

9. Pins are Do Not Use (DNU) on devices without USB. The pin must be left floating.

10. 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.
