Datasheet
Pentium III Processor for the PGA370 Socket at 500 MHz to 1.13 GHz
SC242 - The 242-contact slot connector (previously referred to as slot 1 connector) that the
S.E.C.C. and S.E.C.C. 2 plug into, just as the Intel
Pentium Pro processor uses socket 8.
The cache and L2 cache are an industry designated names.
1.1.2
Processor Naming Convention
A letter(s) is added to certain processors (e.g., 600EB MHz) when the core frequency alone may
not uniquely identify the processor. Below is a summary of what each letter means as well as a
table listing all the available Pentium III processors for the PGA370 socket.
“B” — 133 MHz System Bus Frequency
“E” — Processor with “Advanced Transfer Cache” (CPUID 068xh and greater)
NOTES:
1. Refer to the Pentium III Processor Specification Update for the exact CPUID for each processor.
2. ATC = Advanced Transfer Cache. ATC is an L2 Cache integrated on the same die as the processor core.
With ATC, the interface between the processor core and L2 Cache is 256-bits wide, runs at the same
frequency as the processor core and has enhanced buffering.
