3.4.3.6 AM64x/AM243x Power
The Core voltage of the AM64x/AM243x can be powered by 0.75 V or 0.8 V or 0.85 V based on
the power optimization requirement. It is recommended to use a single voltage source when the SoC
Core voltage (VDD_CORE) and SoC Array Core Voltage (VDDR_CORE) and other array core voltages
(VDDA_0P85_SERDES0_C, VDDA_0P85_SERDES0, VDDA_0P85_USB0, VDD_DLL_MMC0, VDD_MMC0) is
0.85 V. In cases where the SoC Core voltage is required to be 0.75 V or 0.8 V and SoC Array Core Voltage and
other Array Core voltages is required to be 0.85 V then there needs to be separate voltage supply for the SoC
Core voltage and an separate supply for the SoC Array Core voltages.
This EVM has a provision for providing single voltage supply or different voltage supply to the SoC Core
and SoC Array Core and other Array Core Voltages and based requirement. This can be configured by the
placement of resistors as mentioned in
Figure 3-8 .

Note
• PROC101x-001 BOM variant, implements the AM6442 and requires 0.75 V supplied to the
VDD_CORE and 0.85 V supplied to VDDR_CORE. In this variant R2 and R4 are installed by
default and VDD_CORE supply (U25) is setup for 0.75 V operation.
• PROC101x-002 BOM variant, implements the AM2434 and requires 0.85 V supplied to
VDD_CORE and VDDR_CORE. In this variant R1 and R3 are installed by default and VDD_CORE
supply (U25) is setup for 0.85 V operation.
