Specification Update
The "E" and "B" designators distinguish between Pentium® III processors with the
same core frequency
implementations.
The "E" and "B" designators distinguish between Pentium® III processors with the
same core frequency
implementations.
B = 133 MHz System Bus
E = Processors with "Advanced Transfer Cache" (CPUID 068x and greater only if a
frequency overlap exists)
If, for a given core frequency, Pentium III processors are only available with one
system bus frequency and one cache implementation, the above designators will not be
used (e.g., not all processors with "Advanced Transfer Cache" will have the "E"
designation).
Speeds will be marked as MHz up to but not including 1GHz. Speeds 1GHz and above
will have the GHz marking.
Vcc = 1.80V. Tj = 60 C for this 1.13 GHz processor with CPUID 0686.
Tj = 80 C, Vcc = 1.70v.
Vcc = 1.65V.
Vcc = 1.70V for these cCX core steppings. Tj = 70 C for 1.0 GHz. Tj = 75 C for 933
MHz.
This SL4WM S-spec part has a VID request of 1.70V, however the processor should be
supplied 1.76V at the PGA Vcc pins. See Pentium® III datasheet for further
information.
Vcc=1.75V for cD0 Core Stepping (CPUID 068Ah). Tj=77 C for 933MHz and Tj=75 C
1GHz. Tj=80 C for 866MHz to 700MHz.
This processor is valid for low voltage system bus operation at 1.25V AGTL and normal
1.5V AGTL+ signal levels. This processor is also DP capable at the 1.25V AGTL system
bus level. This processor will auto detect differential or single ended clocking.
Vcc=1.75V for cD0 Core Stepping (CPUID 068Ah). Tcase=64 C for 1GHz. Tcase = 67
C for 1.13GHz. This package exists as an FC-PGA2 with Integrated Heat Spreader
(IHS).
These parts are intended for server design applications.
