Intel
Pentium
III Processor with 512KB L2 Cache at 1.13GHz to 1.40GHz
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All specifications in this table apply only to the Intel Pentium III processor with 512KB L2 Cache.
3. Vcc
CORE
and Icc
CORE
supply the processor core and the on-die L2 cache.
4. V

TT
be held to 1.25V ±3%
while the processor system bus is static (idle condition). The ±3% range is the required design target; ±9%
will come from the transient noise added. This is measured at the PGA370 socket pins on the bottom side of
the baseboard.
5.
These are the tolerance requirements, across a 20 MHz frequency bandwidth, measured at the
processor socket pin on the soldered-side of the motherboard.
V
CC
must return to within the static
voltage specification within 100
μ
s after a transient event; see the
VRM 8.5 DC-DC Converter Design
Guidelines
for further details.
6. Maximum I
CC
is measured at V
CC
typical voltage and under a maximum signal loading conditions.
7. The current specified is also for AutoHALT state.
8. Maximum values are specified by design/characterization at nominal Vcc
