3.7.2 DC Voltage and Current Specification
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.
4. These voltages are targets only. A variable voltage source should exist on systems in the
event that a different voltage is required. See Section 3.3 and Table 2 for more
information.
5. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE
pins 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 Table 6 and Figure 2 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 Figure 2 for details.
8. V
CCP
must be provided via a separate voltage source and not be connected to V
CC
. This
specification is measured at the pin and recommended to set at 1.05 V typical.
9. This is maximum total current drawn from V
CCP
plane by only the processor. This
specification does not include the current coming from R
TT
(through the signal line). Refer
to the Intel(R) IMVP-6 Mobile Processor Voltage Regulation Specification to determine the
total I
TT
drawn by the system. This parameter is based on design characterization and is
not tested.
10. Adherence to the voltage specifications for the processor are required to ensure reliable
processor operation.
