SPRUIY9B May 2021 – October 2023
The SoC Core voltage (VDD_CORE) of the AM64x SoC is set to 0.75V. SoC Array Core Voltage (VDDR_CORE) and other array core voltages (VDDA_0P85_SERDES0_C, VDDA_0P85_SERDES0, VDDA_0P85_USB0, VDD_DLL_MMC0 and VDD_MMC0) are configured to 0.85V and are supplied through a common rail.
The SoC has different IO groups. Each IO group is powered by specific power supplies as given in Table 4-6.
