Unless otherwise noted, all specifications in this table apply to all processor frequencies. 2. All outputs are open drain. 3. VIL is defined as the voltage range at a receiving agent that will be interpreted as a logical low value. 4. VIH is defined as the voltage range at a receiving agent that will be interpreted as a logical high value. 5. VIH and VOH may experience excursions above VTT. 6. The VTT referred to in these specifications refers to instantaneous VTT. 7. IOL is measured at 0.10 * VTT. IOH is measured at 0.90 * VTT. 8. Leakage to VSS with land held at VTT. 9. Leakage to VTT with land held at 300 mV. 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. Datasheet 25
