Catastrophic Thermal Protection
The Mobile Intel Pentium 4 Processor-M supports the THERMTRIP# signal for catastrophic 
thermal protection. Alternatively an external thermal sensor can 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 135°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 of the processor. Refer to 
 for more details on THERMTRIP#.

Signal Terminations, Unused Pins and TESTHI[10:0]
All NC pins must remain unconnected. Connection of these pins to V
CC
, V
SS
, or to any other signal 
(including each other) can result in component malfunction or incompatibility with future Mobile 
Intel Pentium 4 Processor-M. See 
 for a pin listing of the processor and the location of 
all NC pins.
