NOTES:
1. All power measurements taken with CMOS inputs driven to V
CC
P and to 0 V.
2. Maximum values are measured at typical V
CC
P to take into account the thermal time constant of the package. Typical
values not tested, but imply the maximum power one should see when running normal high power applications on most
devices. When designing a system to the typical power level, there should be a failsafe mechanism to guarantee control
of the CPU T
C
specification in case of statistical anomalies in the workload. This workload could cause a temporary rise
in the maximum power.
3. Power specifications for 512K L2 components are PRELIMINARY. Consult your FAE.
4. Max values are measured at typical V
CC
P by asserting the STPCLK# pin or executing the HALT intruction (Auto Halt)
with the EBL_CR_POWERON Low_Power_Enable bit set to enabled. See Model Specific Registers in Appendix C of the
Pentium® Pro Processor Developer’s Manual, Volume 3: Operating System Writer’s Guide
(Order Number 242692).
Minimum values are guaranteed by design/characterization at minimum V
CC
P.

S is 0 A when the L2 die receives its power
from the V
