§ 

THERMTRIP#

Output

The processor protects itself from catastrophic overheating by use of an internal 
thermal sensor. This sensor is set well above the normal operating temperature to 
ensure that there are no false trips. The processor stops all execution when the 
junction temperature exceeds approximately 125 °C. This is signalled to the 
system by the THERMTRIP# (Thermal Trip) pin.

TMS

Input

TMS (Test Mode Select) is a JTAG specification support signal used by debug tools.

TRDY#

Input

TRDY# (Target Ready) is asserted by the target to indicate that it is ready to 
receive a write or implicit writeback data transfer. TRDY# must connect the 
appropriate pins of both FSB agents.

TRST#

Input

TRST# (Test Reset) resets the Test Access Port (TAP) logic. TRST# must be driven 
low during power on Reset. 

V

CC

Input

Processor core power supply.

V

SS

Input

Processor core ground node.

V

CCA

Input

V

CCA

 provides isolated power for the internal processor core PLL’s. 

V

CCP

Input

Processor I/O Power Supply.

V

CC_SENSE

Output

V

CC_SENSE

 

together with V

SS_SENSE

 

are voltage feedback signals to Intel® MVP-6 

that control the 2.1-m

Ω

 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 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 

 for definitions of these pins. The VR must supply the voltage that is 

requested by the pins, or disable itself.

V

SS_SENSE

Output

V

SS_SENSE

 

together with V

CC_SENSE

 

are voltage feedback signals to Intel MVP-6 

that control the 2.1-m

Ω

 loadline at the processor die. It should be used to sense 

ground near the silicon with little noise.
