Device Overview

Summary

NOT RECOMMENDED FOR NEW DESIGN

The EMC2300 is an environmental monitoring device with automatic fan control capability. This ACPI compliant device provides hardware monitoring for up to two voltages and three thermal zones, measures the speed of up to four fans, and controls the speed of multiple DC fans using Pulse Width Modulator (PWM) outputs. High frequency and low frequency PWMs are supported.

The EMC2300 hardware monitor provides analog inputs for monitoring the processor voltage Vccp. This device has the capability to monitor its own internal VCC power supply, which may be connected to either main power (VCC) or the suspend power well (VTR).

The EMC2300 hardware monitor includes support for monitoring three thermal zones: two external and one internal. The external temperatures are measured via thermal diode inputs capable of monitoring remote devices. In addition, the EMC2300 is equipped with an ambient temperature sensor for measuring the internal temperature.

Please consider this device EMC2303, EMC1413
