Notes

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. For more information, see AN72845, Design Guidelines for QFN Devices.

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