VCCSENSE Output

VCCSENSE together with VSSSENSE are voltage feedback signals

that control the 2.1 mΩ loadline at the processor die. It should be

used to sense voltage near the silicon with little noise.

VID[6:0] Output

VID[6:0] (Voltage ID) pins are used to support automatic selection

of power supply voltages (V

). Unlike some previous generations

of processors, these are CMOS signals that are driven by the

processor. The voltage supply for these pins must be valid before

the VR can supply V

to the processor. Conversely, the VR output

must be disabled until the voltage supply for the VID pins becomes

valid. The VID pins are needed to support the processor voltage

specification variations. See Table 2 for definitions of these pins.

The VR must supply the voltage that is requested by the pins, or

disable itself.

VSSSENSE Output

VSSSENSE

together with VCCSENSE are voltage feedback signals

that control the 2.1-mΩ loadline at the processor die. It should be

used to sense ground near the silicon with little noise.
