Notes
Document Number: 001-53413 Rev. *K
11. Pins are Do Not Use (DNU) on devices without USB. The pin must be left floating.
12. This feature on select devices only. See
13. 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,
The two pins labeled Vddd must be connected together.
The two pins labeled Vccd must be connected together, with capacitance added, as shown in
page 28. The trace between the two Vccd pins should be as short as possible.
The two pins labeled Vssd must be connected together.
it should be electrically floated and not connected to any other signal.
