2.4.2
Catastrophic Thermal Protection
The mobile Celeron processor 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
Section 5.2 for more details on THERMTRIP#.
2.5
Signal Terminations, Unused Pins and TESTHI[11:0]
All NC pins must remain unconnected. Connection of these pins to VCC, VSS, or to any other signal
(including each other) can result in component malfunction or incompatibility with future mobile
Celeron processors. See Section 5.1 for a processor pin listing and the location of all NC pins.
