Circuit
Description
GNDA
GNDD
P
–
These pins should be connected directly to the ground plane.
V3P3A
V3P3D
P
–
A 3.3V power supply should be connected to these pins.
6.2
Analog Pins
Name

Sense Inputs: These pins are voltage inputs to the internal A/D
converter. Typically, they are connected to either the outputs of
current sensors or the outputs of resistor dividers (voltage sensors).
Unused pins must be connected to V3P3.
VREF
O
8
Voltage Reference for the ADC. This pin is left unconnected. Never
use as an external reference.
XIN
XOUT
I
7
Crystal Inputs. A 32 kHz crystal should be connected across these
pins. Typically, a 27 pF capacitor is also connected from each pin to
GND. It is important to minimize the capacitance between these
pins. See the crystal manufacturer datasheet for details.
Pin types: P = Power, O = Output, I = Input, I/O = Input/Output
The circuit number denotes the equivalent circuit, as specified under “I/O Equivalent Circuits”.
