battery life estimates and power budgeting. Breakdown is as follows: < 4 mA on 
V1P8A, < 15 mA on V1P0A, < 1 mW on V1P35U/V3P3A/V1P24A.

 list the DC specifications for the SoC power rails. They are valid 

only while meeting specifications for junction temperature, clock frequency, and input 
voltages. Care should be taken to read all notes associated with each parameter.

NOTES:
1. Each SoC is programmed with voltage identification value (VID), which is set at manufacturing 

and cannot be altered. Individual VID values are calibrated during manufacturing such that 
two SoCs at the same frequency may have different settings within the VID range above. VID 
targets employed by the SoC during a power management event are selected within the range 
uniquely hard-coded into each SoC.

2. See the VR12/IMVP7 Pulse Width Modulation specification for additional details. Either value is 

ok.

The VID specifications for the SoC CORE_VCC_S3 and UNCORE_VNN_S 3are defined by 
the IMVP7 Pulse Width Modulation (PWM) Specification. 

 specifies the voltage 

level corresponding to the eight bit VID value transmitted over serial VID (SVID) 
interface per IMVP7 specification. A ‘1’ in this table refers to a high voltage level and a 
‘0’ refers to a low voltage level. If the voltage regulation circuit cannot supply the 
voltage that is requested, the voltage regulator must disable itself. The SVID signals
