Warning!
Do not connect any power supply to the voltage supply outputs nor short circuit them to GND, as this
may damage the Mars XU3 SoC module.

Power Consumption

Please note that the power consumption of any MPSoC device strongly depends on the application (on the
configured bitstream and I/O activity).
To estimate the power consumption of your design, please use the Xilinx Power Estimator available on the
Xilinx website.
2.11.6

Heat Dissipation

High performance devices like the Xilinx Zynq Ultrascale+ MPSoC need cooling in most applications; always
make sure the MPSoC is adequately cooled.
For Enclustra Mars modules an Enclustra heat sink is available for purchase along with the product. It repre-
sents an optimal solution to cool the Mars XU3 SoC module- it is low profile (less than 7 mm tall) and covers
the whole module surface. It comes with a gap pad for the MPSoC device and four screws to attach it to the
6
The maximum available output current depends on your MPSoC design. See sections 2.11.1 and 2.11.5 for details.
