Electrical Specifications9. VCC L2 /VCC 3.3 and I CCL2 /I CC3.3 supply the second level cache (“Discrete” cache type only). Unless otherwisenoted, this specification applies to all Pentium III processor cache sizes. Systems should be designed forthese specifications, even if a smaller cache size is used.10.Max ICC measurements are measured at VCC max voltage, maximum temperature, under maximum signalloading conditions. The Max Icc currents specified do not occur simultaneously under the stressmeasurement condition.11.Voltage regulators may be designed with a minimum equivalent internal resistance to ensure that the outputvoltage, at maximum current output, is no greater than the nominal (i.e., typical) voltage level of VCC CORE(VCC CORE_TYP ). In this case, the maximum current level for the regulator, Icc CORE_REG , can be reduced fromthe specified maximum current Icc CORE _MAX and is calculated by the equation:Icc CORE_REG = Icc CORE_MAX × VCC CORE_TYP / (VCC CORE_TYP + VCC CORE Tolerance, Transient)12.The current specified is the current required for a single Pentium III processor. A similar amount of current isdrawn through the termination resistors on the opposite end of the AGTL+ bus, unless single-endedtermination is used (see Section 2.1).13.The current specified is also for AutoHALT state.14.Maximum values are specified by design/characterization at nominal VCC CORE and nominal VCC L2 /VCC 3.3 .15.Based on simulation and averaged over the duration of any change in current. Use to compute the maximuminductance tolerable and reaction time of the voltage regulator. This parameter is not tested.16.dI CC /dt specifications are measured and specified at the SC242 connector pins.17.VCC 5 and ICC 5 are not used by the Pentium III processors. The VCC 5 supply is used for the test equipmentand tools.18.This specification applies to the Pentium III processor with CPUID=067xh.19.This specification applies to the Pentium III processor with CPUID=068xh.20.Max I CC measurements are measured at VCC nominal voltage, maximum temperature, under maximumsignal loading conditions. The Max Icc currents specified do not occur simultaneously under the stressmeasurement condition.21..This specification applies to the Pentium III processor with CPUID=0683h operating at 1.0 GHz.30 Datasheet
