COMX-CORE Series Installation and Use (6806800K11F) 37
The PECI is a one-wire interface that provides a communication channel between a PECI client
(the processor) and a PECI master (the PCH).
The processor digital thermal sensor (DTS) provides an improved capability to monitor device
hot spots, which inherently leads to more varying temperature readings over short time
intervals.
Within the processor, the DTS converts an analog signal into a digital value representing the
temperature relative to PROCHOT# circuit activation. Processor digital thermal sensor controls
processor temperature by modulating (starting and stopping) the processor core clocks when
the processor silicon reaches its maximum operating temperature. A pin "PROCHOT#" is used
in this mode, when PROCHOT# is output and active, it indicate that processor thermal control
circuit is activated. When the PROCHOT# is input from ISL62882, it indicate the VRM
temperature is out of specified value, the processor TTC is activated.
When the CPU junction temperature is more than 125C, CPU will assert the THERMTRIP#.
Signal stop all bus activity and the core power must be shut down in the specified time.
2.3 Unpacking and Inspecting the Module
Damage of Circuits
Electrostatic discharge and incorrect installation and removal of the product can damage
circuits or shorten their life.
Before touching the product make sure that your are working in an ESD-safe environment
or wear an ESD wrist strap or ESD shoes. Hold the product by its edges and do not touch any
components or circuits.
