Datasheet
Intel
Pentium
III Processor with 512KB L2 Cache at 1.13GHz to 1.40GHz

Maximum Ratings
Table 6
contains processor stress ratings only. Functional operation at the absolute maximum and
minimum is not implied nor guaranteed. The processor should not receive a clock while subjected
to these conditions. Functional operating conditions are given in the timing and level tables in
Section 2.10
through
Section 2.12
. Extended exposure to the maximum ratings may affect device
reliability. Furthermore, although the processor contains protective circuitry to resist damage from
static electric discharge, one should always take precautions to avoid high static voltages or electric
fields.
NOTES:
1. Input voltage can never exceed V
SS
+1.78 volts.
2. Input voltage can never exceed V
SS
+ 2.08 volts.
3. Input voltage can never go below -0.3V
4. Parameter applies to CMOS, APIC, and TAP bus signal groups only.

Processor Voltage Level Specifications
The processor voltage level specifications in this section are defined at the PGA370 socket pins
(bottom side of the motherboard). See
Section 7.0
for the processor signal descriptions and
Section
5.4
for the signal listings.
Most of the signals on the processor system bus are in the AGTL signal group. These signals are
specified to be terminated to 1.25V. The voltage level specifications for these signals are listed in
Table 10 on page 28
.
To allow connection with other devices, the clock, CMOS, APIC, and TAP signals are designed to
interface at non-AGTL levels. The voltage level specifications for these pins are listed in
Table 11
on page 28
.
Table 7
through
Table 13
list the voltage level specifications for the Intel
Pentium
III
processor
with 512KB L2 Cache. Specifications are valid only while meeting specifications for junction
temperature, clock frequency, and input voltages. Care should be taken to read all notes associated
with each parameter.
