 supply the second level cache (“Discrete” cache type only). Unless otherwise 

noted, this specification applies to all Pentium III processor cache sizes. Systems should be designed for 
these specifications, even if a smaller cache size is used.

 max voltage, maximum temperature, under maximum signal 

loading conditions. The Max Icc currents specified do not occur simultaneously under the stress 
measurement condition.

11. Voltage regulators may be designed with a minimum equivalent internal resistance to ensure that the output 

voltage, at maximum current output, is no greater than the nominal (i.e., typical) voltage level of V

CCCORE

 

(V

CCCORE_TYP

). In this case, the maximum current level for the regulator, Icc

CORE_REG

, can be reduced from 

the specified maximum current Icc

CORE _MAX

 and is calculated by the equation:

 = Icc

12.The current specified is the current required for a single Pentium III processor. A similar amount of current is 

drawn through the termination resistors on the opposite end of the AGTL+ bus, unless single-ended 
termination is used (see 

).

13.The current specified is also for AutoHALT state.
14.Maximum values are specified by design/characterization at nominal V

18.This specification applies to the Pentium III processor with CPUID=067xh.
19.This specification applies to the Pentium III processor with CPUID=068xh.
