Description
GND
C4
-
Power Ground reference for logic and I/O pins.

GNDA
A5
-
Power The ground reference for the analog circuits (
B5
Analog Comparators, etc.). These are separated
from GND to minimize the electrical noise contained
on VDD from affecting the analog functions.
Power
LDO
E3
-
Power Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. The LDO pin must also be
connected to the VDDC pins at the board level in
addition to the decoupling capacitor(s).
VDD
K7
-
Power Positive supply for I/O and some logic.
G12
K8
C10
K9
H10
G10
E10
D10
D11
G11
VDDA
C7
-
Power The positive supply for the analog circuits (ADC,
C6
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 Table 20-2 on page 775 , regardless
of system implementation.
VDDC
F3
-
Power Positive supply for most of the logic function,
D3
including the processor core and most peripherals.
G3
The voltage on this pin is 1.3 V and is supplied by
C3
the on-chip LDO. The VDDC pins should only be
connected to the LDO pin and an external capacitor
as specified in Table 20-6 on page 780 .
