Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
The ground reference for the analog circuits
(ADC, Analog Comparators, etc.). These are
separated from GND to minimize the electrical
noise contained on VDD from affecting the
analog functions.

Low drop-out regulator output voltage. This
pin requires an external capacitor between
the pin and GND of 1 µF or greater. When the
on-chip LDO is used to provide power to the
logic, the LDO pin must also be connected to
the VDD25 pins at the board level in addition
to the decoupling capacitor(s).
Main oscillator crystal input or an external
clock reference input.
