I/O ¹⁾ Function
-
Supply voltage; Connected to 5V voltage with reverse protection diode
and filter against EMC; Both pins must be connected to the supply without
parasitic resistors
-
Ground; common ground for digital, analog and power; Pins must be
connected together without parasitic resistors
-
Cooling TAB (bottom side); Internally connected to ground; Pin must be
connected externally to ground without parasitic resistors
