E-pad
Connect to VSS for best
mechanical, thermal and
electrical performance
Floating, not connected to
any other signal

Legend: I = Analog Input, O = Analog Output, DIO = Digital Input/Output, CS = CapSense Button,
PS = Proximity Sensor, SH = Shield Electrode, BUZ = Buzzer Output, SPO = Special Purpose Output.
Note
2. The center pad on the QFN package should be connected to ground (VSS) for best mechanical, thermal, and electrical performance. If it is not connected to ground,
it should be left floating without being connected to any other signal.
