DescriptionBuffer TypePin TypePin NamePin Number
Positive supply for most of the logic function, including the
processor core and most peripherals. The voltage on this pin is
1.2 V and is supplied by the on-chip LDO. The VDDC pins should
only be connected to each other and an external capacitor as
specified in Table 32-15 on page 2114 .

The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to minimize
the electrical noise contained on VDD from affecting the analog
functions. VDDA pins must be supplied with a voltage that meets
the specification in , regardless of system implementation.
Power-VDDA
F3
A reference voltage used to specify the voltage at which the ADC
converts to a maximum value. This pin is used in conjunction with
VREFA-, which specifies the minimum value . The voltage that is
applied to VREFA+ is the voltage with which an AINn signal is
converted to 4095. The VREFA+ voltage is limited to the range
specified in Table 32-44 on page 2136.
