Catastrophic Thermal Protection

The Pentium M processor supports the THERMTRIP# signal for catastrophic thermal protection.
An external thermal sensor should also be used to protect the processor and the system against
excessive temperatures. Even with the activation of THERMTRIP#, which halts all processor
internal clocks and activity, leakage current can be high enough such that the processor cannot be
protected in all conditions without the removal of power to the processor. If the external thermal
sensor detects a catastrophic processor temperature of 125 °C (maximum), or if the THERMTRIP#
signal is asserted, the VCC supply to the processor must be turned off within 500 ms to prevent
permanent silicon damage due to thermal runaway.
