The SOM is based on a custom MPSoC. Designing the SOM power follows the same design practices. Signaling is provided to help with this, and it is recommended that you split the power system on your carrier card into three power domains:
- Always On Power Domain
- The +5 V main power and auxiliary power support infrastructure components such as the power management and telemetry circuits, reset circuits, and clocking circuits.
- PS Power Domain
- The power rails that support the peripherals connected to the PS MIO and PS-GTR signals.
- PL Power Domain
- The power rails that support the peripherals connected to the PL HDIO and HPIO signals and the VCCO rails.
