Datasheet

TMS

Input

TMS (Test Mode Select) is a JTAG specification support signal used 
by debug tools.
Please contact your Intel representative for termination 
requirements

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

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-mΩ loadline at the processor die. 

It should be used to sense or measure power 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 V

CC

 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-mΩ loadline at the processor die. It 
should be used to sense or measure ground near the silicon with 
little noise.
