Package Mechanical Specifications and Pin Information
§
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.
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.

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
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
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.
