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.

PECI Bus Architecture
The PECI architecture based on wired OR bus which the clients (as the processor
PECI) can pull up high (with strong drive).
PECI) can pull up high (with strong drive).
The idle state on the bus is near zero.
demonstrates PECI design and connectivity, while the host / originator can
be 3rd party PECI host, and one of the PECI client is the processor PECI device.
