The 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 degree Celsius (maximum), or 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 the thermal runaway of the processor. THERMTRIP# functionality is not 

ensured if the PWRGOOD signal is not asserted.

The following are the general types of reserved (RSVD) signals and connection 

guidelines:

•

RSVD - these signals should not be connected

•

RSVD_TP - these signals should be routed to a test point

•

RSVD_NCTF - these signals are non-critical to function and may be left un-

connected

Arbitrary connection of these signals to V

CC

, V

SS

, or to any other signal (including each 

other) may result in component malfunction. Refer to 

 for a land listing of the 

processor and the location of all reserved signals.
