NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data.
2. Individual processor VID values may be calibrated during manufacturing such that two devices at the same speed may have
different VID settings.
3. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is re-
quired. See Section 2.3 and Table 3 for more information.
4. 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 oscillo-
scope probe.
5. Refer to Tab le 1 0/Figure 2 or Ta ble 11/Figure 3 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. Moreover,
V
CC
should never exceed the VID voltage. Failure to adhere to this specification can shorten the processor lifetime.
6. I
CC_MAX
is specified at V
CC_MAX
7. The current specified is also for the AutoHALT State.
8. I
CC
Stop-Grant and I
CC
Sleep are specified at V
CC_MAX
.
9. The maximum instantaneous current the processor will draw while the thermal control circuit is active as indicated by the as-
sertion of PROCHOT# is the same as the maximum I
CC
for the processor.
