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.

Table 1. Power Pins
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
