The power pins include major power domains for the logic, the small circuits for analog and digital circuits, and the power for I/O blocks.
Inter-Dependencies
The power domain inter-dependencies are described in the Power chapter, including how the power pins connect to the power domains as shown in the Power Diagram section.
Electrical Specifications
The power pin specifications are provided in the data sheets listed in References.
Power Design Tools
For current designs with the Versal device, see the Xilinx Power Estimator (XPE) design tool for estimating power consumption and providing power sequence and thermal information.

Pin List
The power pins are listed in the following table.
| Pin Name | Power Supply Description |
|---|---|
| Platform Management Controller | |
| VCC_BATT | Battery-backed power domain. When VCC_BATT is not used, connect to ground. |
| VCC_FUSE | eFUSE programming. Ideally VCC_FUSE should only be powered up when eFUSE programming is being done. If not programming eFUSE in the field, VCC_FUSE should be connected to ground. |
| VCC_PMC | PMC power domain |
| VCCAUX_PMC | Auxiliary for the PMC |
| VCCAUX_SMON | Analog for the ADC and other analog circuits in the system monitor |
| VCCO_500 | PMC MIO bank 0 with dedicated analog signals DIO_A |
| VCCO_501 | PMC MIO bank 1 |
| VCCO_503 | PMC dedicated I/O (DIO) bank |
| Processing System | |
| VCC_PSFP | PS full-power domain (FPD) |
| VCC_PSLP | PS low-power domain (LPD) |

| VCC_SOC | NoC, NPI, and DDRMC SoC power domain (SPD) |
| VCCAUX | Auxiliary circuits |
| VCCINT | Internal logic (programmable logic, integrated hardware |
| I/O Connectivity | |
| VCC_IO | XPIO banks |
