NOTES:
1.

Unless otherwise noted, all specification in this table are based on estimates and 
simulation or empirical data. These specifications will be updated with characterized data 
from silicon measurements at a later date.

2.

Adherence to the voltage specification for the processor are required to ensure reliable 
processor operation.

3.

Each processor is programmed with a maximum valid voltage identification value (VID), 
which is set at manufacturing and can not be altered. Individual maximum VID values are 
calibrated during manufacturing such that two processors at the same frequency may have 
different settings within the VID range. Please note this differs from the VID employed by 
the processor during a power management event (Thermal Monitor 2). 

4.

These voltages are targets only. A variable voltage source should exist on systems in the 
event that a different voltage is required. See 

 and 

 for more 

information.

5.

The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE 
lands at the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe 
capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the 
probe should be less than 5 mm. Ensure external noise from the system is not coupled into 
the oscilloscope probe.

6.

Refer to 

 for the minimum, typical, and maximum V

CC

 allowed for a 

given current. The processor should not be subjected to any V

CC

 and I

CC

 combination 

wherein V

CC

 exceeds V

CC_MAX

 for a given current.

7.

I

CC_MAX

 specification is based on the V

CC_MAX 

loadline. Refer to
