Thermal Specifications and Design Considerations
This section provides needed data for designing a thermal solution. The LV Intel Pentium
processor 512K uses micro flip-chip ball-grid-array packaging technology and has a junction
temperature (T
) specified at 100º C.

Thermal Specifications

Table 29
provides the thermal design power dissipation and maximum temperatures for the LV
Intel Pentium
processor 512K. Systems should design for the highest possible processor power,
III
even if a processor with a lower thermal dissipation is planned. A thermal solution should be
designed to ensure the junction temperature never exceeds these specifications.

NOTES:
1. These values are specified at nominal Vcc
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.

THERMTRIP# Requirement
In the event the processor drives the THERMTRIP# signal active during valid operation, both the

processor. Valid operation refers to the operating conditions where the THERMTRIP# signal is
guaranteed valid. The time required from THERMTRIP# asserted to V
is 5 seconds and THERMTRIP# asserted to V
