Main Power Supplies

V – PS Internal Logic Supply
CCPINT
V is a 1.0V nominal supply that powers all of the PS internal logic circuits. This supply
CCPINT
can be combined with V
down independent of the PS.
V – PS Auxiliary Logic Supply
CCPAUX
V is a 1.8V nominal supply that powers all of the PS auxiliary circuits. One of the
CCPAUX
0.47 µF capacitors must have less than a 200 mil (5.1 mm) total PCB trace length from the
