2.6.2 DC Voltage and Current Specification
NOTES:
1. 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. Note that this differs from the VID employed by the
processor during a power management event (Thermal Monitor 2, Enhanced Intel
SpeedStep
®
technology, or Extended HALT State).
2. 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.
3. These voltages are targets only. A variable voltage source should exist on systems in the
event that a different voltage is required. See Section 2.3 and Table 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 5 and Figure 1, 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.
6. I
CC_MAX
specification is based on V
CC_MAX
loadline. Refer to Figure 1 for details.
