Figure 5-1 shows anoverview of those domains.Main Power SuppliesV CCPINT – PS Internal Logic SupplyV CCPINT is a 1.0V nominal supply that powers all of the PS internal logic circuits. This supplycan be combined with V CCINT if the system does not require the PL supply to be powereddown independent of the PS.V CCPAUX – PS Auxiliary Logic SupplyV CCPAUX is a 1.8V nominal supply that powers all of the PS auxiliary circuits. One of the0.47 μF capacitors must have less than a 200 mil (5.1 mm) total PCB trace length from theX-Ref Target - Figure 5-1Figure 5-1: Power DomainsUG933_c5_01_051212VCCPAUXVCCPLLV CCPINTProcessing System (PS)VCCO_MIO0 VCCO_DDR V CCO_MIO1VCCAUXVCCINTProgrammable Logic (PL)VCCO0 V CCO1 VCCOnSend Feedback
