§
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
CC
). 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
CC
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.
