THERMTRIP#

Thermal Trip: The processor protects itself from catastrophic 

overheating by use of an internal thermal sensor. This sensor is set 

well above the normal operating temperature to ensure that there are 

no false trips. The processor will stop all execution when the junction 

temperature exceeds approximately 130 °C. This is signaled to the 

system by the THERMTRIP# pin.

The processor requires this input signal to be a clean indication that 

the V

, power supplies are stable and 

within specifications. This requirement applies, regardless of the S-

state of the processor. 'Clean' implies that the signal will remain low 

(capable of sinking leakage current), without glitches, from the time 

that the power supplies are turned on until they come within 

specification. The signal must then transition monotonically to a high 

state. This is connected to the PCH PROCPWRGD signal.

SKTOCC# 

Detect): Pulled down directly (0 Ohms) on the processor package to 

ground. There is no connection to the processor silicon for this signal. 

System board designers may use this signal to determine if the 

processor is present.
