2.6.15.5 AM62x SoC Power

The Core voltage of the AM62x can be 0.75 V or 0.85 V based on the Rfb(R150) Resistor value and on the power optimization requirement. By Default Rfb = 41.2K will be mounted (VDD_CORE = 0.85 V), it can be changed to 0.75 V by changing the Rfb to 24.9K. Current monitors are provided on all the SoC Power rails.

The SoC has different IO groups. Each IO group is powered by specific power supplies as shown in Table 2-14.
