Electrical Specifications
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. Instantaneous current I
CC_CORE_INST
of 30 A has to be sustained for short time (t
INST
) of 10 µs. Average
current is less than maximum specified I
CCDES
. VR OCP threshold should be high enough to support current
levels described herein.
7. Measured at the bulk capacitors on the motherboard.
8. 4-M L2 cache.
9. Based on simulations and averaged over the duration of any change in current. Specified by design/
characterization at nominal V
CC
. Not 100% tested.
10. This is a power-up peak current specification, which is applicable when V
CCP
is high and V
CC_CORE
is low.
11. This is a steady-state I
CC
current specification, which is applicable when both V
CCP
and V
CC_CORE
are high.
12. Processor I
CC
requirements in Intel Dynamic Acceleration Technology mode is lesser than Icc in HFM.
13. The maximum delta between Intel Enhanced Deeper Sleep and LFM on the processor is lesser than or
equal to 350 mV.
