Description

VID[6:0]

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

selection of power supply voltages (VCC). 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 VCC 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 3 for definitions of these pins. The VR must supply the

voltage that is requested by the pins, or disable itself.

VCCP

PWR

Processor I/O Power Supply which needs to remain on in Deep

Power Down Technology (C6) state.

VCCPC6

PWR

Processor I/O Power Supply which needs to remain on in Deep

Power Down Technology (C6) state.

VCC_SENSE

VCC_SENSE is an isolated low impedance connection to the

processor core power (VCC). It can be used to sense or measure

power near the silicon with little noise.

VSS_SENSE

VSS_SENSE is an isolated low impedance connection to

processor core VSS. It can be used to sense or measure ground

near the silicon with little noise.
