NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical
data. These specifications will be updated with characterized data from silicon measurements at a later date.
VID range VID 1.200 — 1.425 V

2. Each processor is programmed with a maximum valid voltage identification value (VID), which is set at man-
ufacturing 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 or
Enhanced HALT State).

3. These voltages are targets only. A variable voltage source should exist on systems in the event that a differ-
ent voltage is required. See Section 2.4 and Table 2-2 for more information.
4. 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.
5. Refer to Table 2-10 and Figure 2-3 for the minimum, typical, and maximum V
CC
allowed for a given current.
The processor should not be subjected to any Vcc and Icc combination wherein V
CC
exceeds V

for a
given current.
