Power and Power-On Sequence

Power Consumption

The maximum power consumption of the Carrier Board depends mainly on the mounted SoM's FPGA design running on the Zynq device.

Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Power InputTypical Current

Table 18: Typical power consumption.

 * TBD - To Be Determined soon with reference design setup.

Power supply with minimum current capability of 3A for system startup is recommended.

To avoid any damage to the module, check for stabilized on-board voltages and VCCIO's before put voltages on PL I/O-banks and interfaces. All I/Os should be tri-stated during power-on sequence.

Power Distribution Dependencies

The Carrier Board needs one single power supply voltage with a nominal value of 5V. Following diagram shows the distribution of the input voltage '5VIN' to the on-board components on the mounted SoM:
