Electrical Specifications
NOTES:
1. The typical values shown are the VID encoded voltages. Static and ripple tolerances (for minimum and
maximum voltages) are defined in the load line tables i.e.,
Table 3-8 through
Table 3-21. Adherence to
loadline specifications for the Pentium M processor is required to ensure reliable processor operation.
2. The voltage specifications are assumed to be measured at a via on the motherboard’s opposite side of the
processor’s socket (or BGA) ball with a 100-MHz bandwidth oscilloscope, 1.5-pF maximum probe
capacitance, and 1-Mohm minimum impedance. The maximum length of ground wire on the probe should be
less than 5 mm. Ensure external noise from the system is not coupled in the scope probe.
3. Specified at VCC,STATIC (nominal) under maximum signal loading conditions.
4. Specified at the VID voltage.
5. The ICCDES(max) specification comprehends future processor HFM frequencies. Platforms should be
designed to this specification.
6. Based on simulations and averaged over the duration of any change in current. Specified by design/
characterization at nominal VCC. Not 100% tested.
7. Measured at the bulk capacitors on the motherboard.
8. Pentium M processors LV and ULV will support VCCA supply voltages of both 1.8 V ±5% and1.5 V ±5%.
9. Deeper sleep voltage of 0.726 V (typical) is supported on LV and ULV Pentium M processors with CPU
signature =06D8h. A typical voltage setting between 0.726 V and 0.748 V may be used but the minimum and
maximum voltages specified in
Table 3-7 should not be exceeded.
10.For 733J, CPU signature = 06D8h.
