O
The VID (Voltage ID) pins can be used to support automatic selection of power
supply voltages. These pins are not signals, but are either an open circuit or a short
circuit to V
supply voltages. These pins are not signals, but are either an open circuit or a short
circuit to V
SS
on the processor. The combination of opens and shorts defines the
voltage required by the processor. The VID pins are needed to cleanly support
voltage specification variations on Intel Celeron processors. See
voltage specification variations on Intel Celeron processors. See
for
definitions of these pins. The power supply must supply the voltage that is requested
by these pins, or disable itself.

These input signals are used by the AGTL+ inputs as a reference voltage. AGTL+
inputs are differential receivers and will use this voltage to determine whether the
signal is a logic high or logic low.

For the FC-PGA/FC-PGA2 packages, V
