Electrical Specifications
3. 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 im-
pedance. 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.
4. Refer to Table 2-9 and Figure 2-2 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 giv-
en current. Moreover, V_CC should never exceed the VID voltage. Failure to adhere to this specification can
shorten the processor lifetime.
5. I_{CC_MAX} is specified at V_{CC_MAX .}
6. The current specified is also for AutoHALT state.
7. I_CC Stop-Grant and I_CC Sleep are specified at V_{CC_MAX .}
8. The maximum instantaneous current the processor will draw while the thermal control circuit is active as in-
dicated by the assertion of PROCHOT# is the same as the maximum I_CC for the processor.
9. These parameters are based on design characterization and are not tested.

NOTES:
1. The loadline specification includes both static and transient limits except for overshoot allowed as
shown in Section 2.12.
2. This table is intended to aid in reading discrete points on Figure 2-3.
3. The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE
pins. Voltage regulation feedback for voltage regulator circuits must be taken from processor VCC
and VSS pins. Refer to the Voltage Regulator-Down (VRD) 10.0 Design Guidelines for Desktop
Socket 478 for socket loadline guidelines and VR implementation details.
