The SoC is a highly integrated component, where many traditional subsystems are 

contained on one die. No on-die voltage regulator exists except for power supplied to 

the internal clock generators and thermal sensors.

A total of 13 external unique rails need to be supplied. 

 shows the voltage rail 

of each external Voltage Regulator (VR), its voltage levels and a list of internal units 

associated with the voltage rail.

The VCC, VNN, VDDQA, and VDDQB rails are sVID-based variable rails and change 

dynamically. Eight of the 13 VR Rails in 

 follow the naming convention of 

including a suffix indicating the power modes in which the rail is active.

• A - Always On (AON). Remains powered during S0-S5 states.
• S - Switched. Remains powered during S0 only.
