Thermal Solution Design and PROCHOT# Behavior

With a properly designed and characterized thermal solution, it is anticipated that PROCHOT# will only be asserted for very short periods of time when running the most power intensive applications. The processor performance impact due to these brief periods of TCC activation is expected to be so minor that it would be immeasurable. However, an under-designed thermal solution that is not able to prevent excessive assertion of PROCHOT# in the anticipated ambient environment may:

  • Cause a noticeable performance loss.
  • Result in prolonged operation at or above the specified maximum junction temperature and affect the long-term reliability of the processor.
  • May be incapable of cooling the processor even when the TCC is active continuously (in extreme situations).
