Electrical Specifications

NOTES:

Each processor is programmed with a maximum valid voltage identification value (VID), which is set at

manufacturing and cannot be altered. Individual maximum VID values are calibrated during manufacturing

such that two processors at the same frequency may have different settings within the VID range. Note

that this differs from the VID employed by the processor during a power management event (Intel Thermal

Monitor 2, Enhanced Intel SpeedStep Technology, or C1E).

The voltage specifications are assumed to be measured across VCCSENSE and VSSSENSE pins at socket with a

100-MHz bandwidth oscilloscope, 1.5-pF maximum probe capacitance, and 1-MΩ 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.

Specified at 100°C Tj.

Specified at the VID voltage.

The ICCDES(max) specification of 19 A comprehends only Intel Core Duo processor LV HFM frequencies.

Based on simulations and averaged over the duration of any change in current. Specified by design/

characterization at nominal VCC. Not 100% tested.

Measured at the bulk capacitors on the motherboard.

VCC, boot tolerance is shown in Figure 3.

This is a steady-state Iccp current specification, which is applicable when both VCCP and VCC core are high.

10.

This is a power-up peak current specification, which is applicable when VCCP is high and VCC core is low.

11.

Specified at the nominal VCC.

12.

If a given Operating System C-State model is not based on the use of MWAIT or I/O Redirection, the

processor Deeper Sleep VID will be same as LFM VID.
