Intelligent electronic device with assured data storage on powerdown

Abstract

An IED includes a power monitoring circuit operative to monitor a parameter of a portion of a power distribution system and generate an analog signal representative thereof. A processor couples with the power monitoring circuit and operates to receive the analog signal and at least one of quantify and report the monitored parameter. The processor further includes an integrated circuit, the integrated circuit having a non-volatile memory operative to store program code for the processor. A digital processing core couples with the non-volatile memory and operates to execute the stored program code to implement the quantifying and reporting functions. A volatile memory couples with the processing core and operates to store working data code for the digital processing core during execution of the stored program code.
