Intel Pentium 4 Processor on 0.13 Micron Process Datasheet
27
Electrical Specifications
NOTES:
1. These voltages are targets only. A variable voltage source should exist on systems in the event that a
different voltage is required. See Table 2-2 for more information. The VID bits will set the maximum VCC with the minimum being defined according to current consumption at that voltage.
2. 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 M
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. Refer to Table 2-7 and Figure 2-4 for the minimum, typical, and maximum VCC allowed for a given current. The processor should not be subjected to any VCC and ICC combination wherein VCC exceeds VCC_MAX for a
given current. Failure to adhere to this specification can affect the long term reliability of the processor.
4. VCC_MIN is defined at ICC_MAX.
5. The current specified is also for AutoHALT State.
6. The maximum instantaneous current that the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT# is the same as the maximum ICC for the processor.
7. ICC Stop-Grant and ICC Sleep are specified at VCC_MAX.
8. These specifications apply to the processor with maximum VID setting of 1.525 V for the Pentium 4
processor with 512-KB L2 cache on 0.13 micron process.
9. This specification applies to both static and transient components. The rising edge of VCCVID must be
monotonic from 0 to 1.1 V. See
Figure 2-1 for current requirements. In this case monotonic is defined as
continuously increasing with less than 50 mV of peak to peak noise for any width greater than 2 ns
superimposed on the rising edge.
10.ICC_MAX is specified for highest VID only. The processor will be shipped under multiple VIDs listed for each
frequency; however, the ICC_MAX specifications will be the same as highest VID specified in table.
11.These specifications apply to the processor with maximum VID setting of 1.550 V for the Pentium 4
processor with 512-KB L2 cache on 0.13 micron process.
12.This specification applies to processors with maximum VID setting of 1.550 V for the Pentium 4 processor
Extreme Edition supporting Hyper-Threading Technology.
13.Refer to Table 2-8 and Figure 2-5 for the minimum, typical, and maximum VCC allowed for a given current. The processor should not be subjected to any VCC and ICC combination wherein VCCexceeds VCC_MAX for a
given current. Failure to adhere to this specification can affect the long term reliability of the processor.
14.These specifications apply to processors with maximum VID setting of 1.600 V for the Pentium 4 processor
Extreme Edition supporting Hyper-Threading Technology.
