NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processors.
2. These voltages are targets only. A variable voltage source should exist on systems in the event that a
3. The voltage specification requirements are measured across vias on the platform for the VCC_SENSE and
VSS_SENSE pins close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe
capacitance, and 1 milliohm 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.
4. The processor should not be subjected to any static VCC level that exceeds the VCC_MAX associated with any
particular current. Moreover, Vcc should never exceed VCC_VID. Failure to adhere to this specification can
shorten the processor lifetime.
5. Maximum current is defined at VCC_MAX.
6. The current specified is also for AutoHALT State.
7. The maximum instantaneous current the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT#.
8. SM_VCC is required for correct operation of the processor VID logic. Refer to Figure 19 for details. 9. This specification applies to the PLL power pins VCCA and VCCIOPLL. See
Section 2.5 for details. This
parameter is based on design characterization and is not tested
10.This specification applies to each GTLREF pin.
11. The loadlines specify voltage limits at the die measured at VCC_SENSE and VSS_SENSE pins. Voltage
regulation feedback for voltage regulator circuits must be taken from processor VCC and VSS pins.
12.Adherence to this loadline specification is required to ensure reliable processor operation.
