Zynq-7000 AP SoC devices are divided into several power domains. Figure 5-1 shows an
overview of those domains.
Main Power Supplies
V
CCPINT
– PS Internal Logic Supply
V
CCPINT
is a 1.0V nominal supply that powers all of the PS internal logic circuits. This supply
can be combined with V
CCINT
if the system does not require the PL supply to be powered
down independent of the PS.
V
CCPAUX
– PS Auxiliary Logic Supply
V
CCPAUX
is a 1.8V nominal supply that powers all of the PS auxiliary circuits. One of the
0.47 µF capacitors must have less than a 200 mil (5.1 mm) total PCB trace length from the
X-Ref Target - Figure 5-1
