Electrical Specifications
The processor
uses eight voltage identification signals, VID[7:0], to support automatic
selection of voltages.
VID[7:0]. A ‘1’ in this table refers to a high voltage level and a ‘0’ refers to a low
voltage level. If the processor socket is empty (VID[7:0] = 11111111), or the voltage
regulation circuit cannot supply the voltage that is requested, the voltage regulator
must disable itself.
voltage level. If the processor socket is empty (VID[7:0] = 11111111), or the voltage
regulation circuit cannot supply the voltage that is requested, the voltage regulator
must disable itself.
The processor
provides the ability to operate while transitioning to an adjacent VID and
its associated processor core voltage (V
CC
). This will represent a DC shift in the
loadline. It should be noted that a low-to-high or high-to-low voltage state change will
result in as many VID transitions as necessary to reach the target core voltage.
Transitions above the maximum specified VID are not permitted.
result in as many VID transitions as necessary to reach the target core voltage.
Transitions above the maximum specified VID are not permitted.
includes VID
step sizes and DC shift ranges. Minimum and maximum voltages must be maintained
as shown in
as shown in
.
The VR used must be capable of regulating its output to the value defined by the new
VID. DC specifications for dynamic VID transitions are included in
VID. DC specifications for dynamic VID transitions are included in
Table 2-1.
