VFQFPN and SO connections

1.

There is an exposed central pad on the underside of the VFQFPN package. This is pulled, internally, to

VSS, and must not be allowed to be connected to any other voltage or signal line on the PCB.

2.

See Package mechanical section for package dimensions, and how to identify pin-1.
