Description

The EMC1043 is a System Management Bus (SMBus) temperature sensor designed for monitoring three temperature zones. It can measure one internal diode and two externally connected diodes. The EMC1043 is specifically designed to operate with AMD processor diodes and can also be configured to measure a standard thermal diode with Resistive Error Correction.
