Platform Environmental Control Interface (PECI)
DC Specifications
PECI is an Intel proprietary interface that provides a communication channel between
Intel processors and chipset components to external Adaptive Thermal Monitor devices.
The processor contains a Digital Thermal Sensor (DTS) that reports a relative die
temperature as an offset from Thermal Control Circuit (TCC) activation temperature.
Temperature sensors located throughout the die are implemented as analog-to-digital
converters calibrated at the factory. PECI provides an interface for external devices to
read the DTS temperature for thermal management and fan speed control. More
detailed information may be found in the Platform Environment Control Interface
(PECI) Specification.
