Pentium
III Processor for the SC242 at 450 MHz to 1.0 GHz
4.1.1
Thermal Diode
The Pentium
III
processor incorporates an on-die diode that may be used to monitor the die
temperature (junction temperature). A thermal sensor located on the baseboard, or a stand-alone
measurement kit, may monitor the die temperature of the Pentium
III
processor for thermal
management or instrumentation purposes.
Table 27
and
Table 28
provide the diode parameter and
interface specifications.
NOTES:
1. Intel does not support or recommend operation of the thermal diode under reverse bias.
2. At room temperature with a forward bias of 630 mV.
3. n_ideality is the diode ideality factor parameter, as represented by the diode equation:
I=Io(e (Vd*q)/(nkT) - 1).
4. This specification applies to the Pentium
III processor with CPUID=067xh.
5. This specification applies to the Pentium
III processor with CPUID=068xh.
