- TableStep1 - 1. Intel does not support or recommend operation of the thermal diode under reverse bias.
- TableStepn - 2. Characterized at 100 C.
- TableStepn - 3. Not 100% tested. Specified by design characterization.
- TableStepn - 4. The ideality factor, n, represents the deviation from ideal diode behavior as exemplified by the diode equation: IFW=Is *(e(qVd/nkT) -1) Where IS = saturation current, q = electronic charge, VD = voltage across the diode, k = ...

Technology
The Mobile Intel Pentium 4 Processor-M, when used in conjunction with the requisite Intel
SpeedStep
technology applet or its equivalent, supports Enhanced Intel SpeedStep technology.
Enhanced Intel SpeedStep technology allows the processor to switch between two core frequencies
automatically based on CPU demand, without having to reset the processor or change the system
bus frequency. The processor operates in two modes, the Maximum Performance mode or the
Battery Optimized mode. Each frequency and voltage pair identifies the operating mode. The
processor drives the VID[4:0] pins with the correct VID for the current operating mode. After
reset, the processor will start in Battery Optimized mode. Any RESET# assertion will force the
