IVT_ID_N

This output can be used by the platform to determine if the installed 

processor is an Intel® Xeon® processor E5-1600 v2 product family, Intel® 

Xeon® processor E5-2600 v2 product family or Intel® Xeon® processor E5-

1600/E5-2600 product families.
This is pulled to ground on the processor package.This signal is also used by 

the VCCPLL and VTT rails to switch their output voltage to support future 

processors.

SKTOCC_N

SKTOCC_N (Socket occupied) is used to indicate that a processor is present. 

This is pulled to ground on the processor package; there is no connection to 

the processor silicon for this signal.

VCC

Variable power supply for the processor cores, lowest level caches 

(LLC), ring interface, and home agent. It is provided by a 

VRM/EVRD 12.0 compliant regulator for each CPU socket. The 

output voltage of this supply is selected by the processor, using the 

serial voltage ID (SVID) bus.

VCC has a Vboot setting of 0.0V and is not included in the 

PWRGOOD indication. Refer to the compatible VR12.0 

PWM controller.

VCC_SENSE
VSS_VCC_SENSE

VCC_SENSE and VSS_VCC_SENSE provide an isolated, low 

impedance connection to the processor core power and ground. 

These signals must be connected to the voltage regulator feedback 

circuit, which insures the output voltage (that is, processor 

voltage) remains within specification. Please see the applicable 

platform design guide for implementation details.

VSA_SENSE
VSS_VSA_SENSE

VSA_SENSE and VSS_VSA_SENSE provide an isolated, low 

impedance connection to the processor system agent (VSA) power 

plane. These signals must be connected to the voltage regulator 

feedback circuit, which insures the output voltage (that is, 

processor voltage) remains within specification. Please see the 

applicable platform design guide for implementation details.

VTTD_SENSE
VSS_VTTD_SENSE

VTTD_SENSE and VSS_VTTD_SENSE provide an isolated, low 

impedance connection to the processor I/O power plane. These 

signals must be connected to the voltage regulator feedback 

circuit, which insures the output voltage (that is, processor 

voltage) remains within specification. Please see the applicable 

platform design guide for implementation details.

VCCD_01 and VCCD_23

Variable power supply for the processor system memory interface. 

Provided by two VRM/EVRD 12.0 compliant regulators per CPU 

socket. VCCD_01 and VCCD_23 are used for memory channels 0, 

1, 2, & 3 respectively. The valid voltage of this supply (1.50V or 

1.35V) is configured by BIOS after determining the operating 

voltages of the installed memory. VCCD_01 and VCCD_23 will also 

be referred to as VCCD. 

The processor must be provided VCCD_01 and VCCD_23 

for proper operation, even in configurations where no 

memory is populated. A VRM/EVRD 12.0 controller is 

recommended, but not required.

VCCPLL

Fixed power supply (1.7V) for the processor phased lock loop 

(PLL).
