Electrical Specifications
NOTES:
1. Each processor is programmed with a maximum valid voltage identification value (VID), which is set at
manufacturing and cannot 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 (Intel Thermal
Monitor 2, Enhanced Intel SpeedStep Technology, or Enhanced Halt State).
2. The voltage specifications are assumed to be measured across V
CC_SENSE
and V
SS_SENSE
pins at 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 in the scope probe.
3. Specified at 100°C Tj.
4. Specified at the nominal V
CC
.
5. 800-MHz FSB Supported
6. Measured at the bulk capacitors on the motherboard.
7. The maximum delta between Intel Enhanced Deeper Sleep and LFM on the processor is lesser than or
equal to 350 mV.
8. Based on simulations and averaged over the duration of any change in current. Specified by design/
characterization at nominal V
CC
. Not 100% tested.
9. This is a power-up peak current specification, which is applicable when V
CCP
is high and V
CC_CORE
is low.
10. This is a steady-state Icc current specification, which is applicable when both V
CCP
and V
CC_CORE
are high.
11. 4-M L2 cache.
12. Intel Dynamic Acceleration Technology not supported.
