Intel Pentium III Processor with 512KB L2 Cache at 1.13GHz to 1.40GHz

Thermal Specifications and Design Considerations
This chapter provides needed data for designing a thermal solution. However, for the correct
thermal measuring processes, refer to Intel Pentium III Processors in the FC-PGA2 Package
Thermal Design Guide (Order Number 249660). The Intel Pentium III processor with 512KB
L2 Cache uses flip chip pin grid array packaging technology with a Integrated Heat Spreader and
has a case temperature (Tcase) specified.
4.1
Thermal Specifications
Table 29 provides the thermal design power dissipation and maximum temperatures for the Intel
Pentium III processor with 512KB L2 Cache. Systems should design for the highest possible
processor power, even if a processor with a lower thermal dissipation is planned. A thermal
solution should be designed to ensure the case temperature never exceeds these specifications.
1. These values are specified at nominal VCCCORE for the processor pins.
2. Processor power includes the power dissipated by the processor core, the L2 cache, and the AGTL bus
termination. The maximum power for each of these components does not occur simultaneously.
3. Processor core power includes only the power dissipated by the core die.
4.1.1
THERMTRIP# Requirement
In the event the processor drives the THERMTRIP# signal active during valid operation, both the
Vcc and Vtt supplies to the processor must be turned off to prevent thermal runaway of the
processor. Valid operation refers to the operating conditions where the THERMTRIP# signal is
guaranteed valid. The time required from THERMTRIP# asserted to Vcc rail at 1/2 nominal is 5S
and THERMTRIP# asserted to Vtt rail at 1/2 nominal is 5S.
