Pentium
III Processor for the SC242 at 450 MHz to 1.0 GHz
NOTES:
1. These values are specified at nominal V
CCCORE
for the processor core and nominal V
CCL2
/V
CC3.3
for the L2
cache (if applicable).
2. Thermal Design Power (TDP) represents the maximum amount of power the thermal solution is required to
dissipate. The thermal solution should be designed to dissipate the TDP without exceeding the maximum
Tjunction specification. TDP does not represent the power delivery and voltage regulation requirements for
the processor.
3. T
is the worst-case difference between the thermal reading from the on-die thermal diode
and the hottest location on the processor’s core.
4. Power density is the maximum power the processor die can dissipate (i.e. processor power) divided by the
die area over which the power is generated.
5. Power for these processors is generated over the entire processor die (see
Figure 40
for processor die
dimensions).
6. Power for these processors is generated over the core area (see
Figure 20
for processor die and core area
dimensions). Thermal solution designs should compensate for this smaller heat flux area (core) and not
assume that the power is uniformly distributed across the entire die area (core + cache).
7. T
JUNCTION
offset values do not include any thermal diode kit measurement error. Diode kit measurement
error must be added to the T
JUNCTION
offset value from the table, as outlined in the Intel
Pentium
III
processor Thermal Metrology for CPUID-068h Family Processors Intel has characterized the use of the
Analog Devices AD1021 diode measurement kit and found its measurement error to be 1 °C.
8. This specification applies to the Pentium
III processor with CPUID=0683h operating at 1.0 GHz.
