Datasheet

An external signal, PROCHOT# (processor hot), is asserted when the processor core 

temperature has reached its maximum operating temperature. If the Thermal Monitor 

is enabled (note that the Thermal Monitor must be enabled for the processor to be 

operating within specification), the TCC will be active when PROCHOT# is asserted. The 

processor can be configured to generate an interrupt upon the assertion or de-

assertion of PROCHOT#. 

As an output, PROCHOT# (Processor Hot) will go active when the processor 

temperature monitoring sensor detects that one or both cores has reached its 

maximum safe operating temperature. This indicates that the processor Thermal 

Control Circuit (TCC) has been activated, if enabled. As an input, assertion of 

PROCHOT# by the system will activate the TCC, if enabled, for both cores. The TCC will 

remain active until the system de-asserts PROCHOT#.

PROCHOT# allows for some protection of various components from over-temperature 

situations. The PROCHOT# signal is bi-directional in that it can either signal when the 

processor (either core) has reached its maximum operating temperature or be driven 

from an external source to activate the TCC. The ability to activate the TCC via 

PROCHOT# can provide a means for thermal protection of system components. 

PROCHOT# can allow VR thermal designs to target maximum sustained current instead 

of maximum current. Systems should still provide proper cooling for the VR, and rely 

on PROCHOT# only as a backup in case of system cooling failure. The system thermal 

design should allow the power delivery circuitry to operate within its temperature 

specification even while the processor is operating at its Thermal Design Power. With a 

properly designed and characterized thermal solution, it is anticipated that PROCHOT# 

would only be asserted for very short periods of time when running the most power 

intensive applications. An under-designed thermal solution that is not able to prevent 

excessive assertion of PROCHOT# in the anticipated ambient environment may cause a 

noticeable performance loss. Refer to the Voltage Regulator-Down (VRD) 11.0 

Processor Power Delivery Design Guidelines For Desktop LGA775 Socket for details on 

implementing the bi-directional PROCHOT# feature.

Regardless of whether or not Thermal Monitor or Thermal Monitor 2 is enabled, in the 

event of a catastrophic cooling failure, the processor will automatically shut down when 

the silicon has reached an elevated temperature (refer to the THERMTRIP# definition in 

). At this point, the FSB signal THERMTRIP# will go active and stay active as 

described in 

. THERMTRIP# activation is independent of processor activity and 

does not generate any bus cycles. If THERMTRIP# is asserted, processor core voltage 

(V

CC

) must be removed within the timeframe defined in
