III Processor for the PGA370 Socket at 500 MHz to 1.13 GHz
18.This specification only applies to 1B GHz S-spec #: SL4WM. This part has a VID request of 1.70 V, however
the processor should be supplied 1.76 V at the PGA Vcc pin by the Voltage Regulator Circuit or VRM.
19.This specification applies only to 1B GHz S-spec #: SL4WM. This value is 60 mV offset from the standard
specification and more at the Minimum specification. These tolerances are measured from a 1.70 V base,
while Vcc supplied is 1.76 V.
20. This processor exists in both FC-PGA and FC-PGA2.
2.10.1 ICC Slew Rate Specifications
This section contains typical current slew rate data for processors covered by this design guideline.
Actual slew rate values and wave-shapes may vary slightly depending on the type and size of
decoupling capacitors used in a particular implementation.
