Catastrophic Thermal Protection
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.

Reserved or Unused Signals
The following are the general types of reserved (RSVD) signals and connection
guidelines:
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
