Pentium
III Processor for the SC242 at 450 MHz to 1.0 GHz
NOTES:
1. Operating voltage is the voltage to which the component is designed to operate. See
Table 7
.
2. Input voltage can never be above V
SS
+ 2.3 V.
3. Input voltage can never be below V
TT
- 2.3 V.
4. Parameter applies to the 2.5 V processor core signals (BCLK, PICCLK, and PWRGOOD).
5. Parameter applies to the 1.5 V processor core signals (all signals except BCLK, PICCLK, and PWRGOOD).
6. The electrical and mechanical integrity of the processor edge fingers are specified to last for 50 insertion/
extraction cycles.
7. While insertion/extraction cycling above 50 insertions will cause an increase in the contact resistance (above
0.1
) and a degradation in the material integrity of the edge finger gold plating, it is possible to have
processor functionality above the specified limit. The actual number of insertions before processor failure will
vary based upon system configuration and environmental conditions.

Processor DC Specifications
The processor DC specifications in this section are defined at the Pentium
III
processor core pins,
edge fingers, and at the SC242 connector pins. See
Section 7.0
for the processor edge finger signal
definitions and
Section 5.0
for the core pin locations and the signal listing.
Most of the signals on the Pentium
III
processor system bus are in the AGTL+ signal group. These
signals are specified to be terminated to 1.5 V. The DC specifications for these signals are listed in
Table 9
.
To allow connection with other devices, the Clock, CMOS, APIC, and TAP signals are designed to
interface at non-AGTL+ levels. The DC specifications for these pins are listed in
Table 10
.
Table 8
through
Table 11
list the DC specifications for Pentium
III
processors. Specifications are
valid only while meeting specifications for case temperature, clock frequency, and input voltages.
Care should be taken to read all notes associated with each parameter.
