2.7.3.1 Platform Environment Control Interface (PECI) DC Specifications
PECI is an Intel proprietary one-wire interface that provides a communication channel
between Intel processors, chipsets, and external thermal monitoring devices. The
processor contains Digital Thermal Sensors (DTS) distributed throughout die. These
sensors are implemented as analog-to-digital converters calibrated at the factory for
reasonable accuracy to provide a digital representation of relative processor
temperature. PECI provides an interface to relay the highest DTS temperature within a
die to external management devices for thermal/fan speed control. More detailed
information may be found in the Platform Environment Control Interface (PECI)
Specification.
