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°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. THERMTRIP# functionality is not guaranteed if the
PWRGOOD signal is not asserted.

Reserved and Unused Pins
All RESERVED (RSVD) 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 processors. See
for a pin listing of the processor
and the location of all RSVD pins.
For reliable operation, always connect unused inputs or bidirectional signals to an
appropriate signal level. Unused active low AGTL+ inputs may be left as no connects if
AGTL+ termination is provided on the processor silicon. Unused active high inputs
should be connected through a resistor to ground (V
SS
). Unused outputs can be left
unconnected.
The TEST1 and TEST2 pin must have a stuffing option connection to V
SS
separately via
1-kΩ, pull-down resistors.
