Pentium III Processor for the SC242 at 450 MHz to 800 MHz
1.1.2
Processor Naming Convention
A letter(s) is added to certain processors (e.g., 600B MHz) when the core frequency alone may not
uniquely identify the processor. Below is a summary what the letter means as well as a table
listing all Pentium III processors currently available.
“B” — 133 MHz System Bus Frequency
“E” — Processor with “Advanced Transfer Cache” (CPUID 068xh)
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.
