1.62V to 3.63V VCC for the GPIO signals.
This supply voltage pin will determine the I/O levels of the
GPIO[15:4] signals.

The center pad on the backside of the QFN package is metallic and
should be connected to GND on the PCB. The thermal pad size on
the PCB should be the approximate size of this center pad and
should be solder mask defined. The solder mask opening should be
at least 0.0025" inwards from the edge of the PCB thermal pad.
