Freescale® Semiconductor, Inc. introduces three types of metering reference designs based on the new Kinetis® M-Series Microcontrollers (MCUs). These MCUs address high accuracy and low-cost needs by providing a high performance 24-bit analog front-end combined with an embedded programmable gain amplifier (PGA) to increase the accuracy of energy measurement. These power meter reference designs were developed to demonstrate the key strengths of the Kinetis M-Series MCUs in a typical automated meter reading (AMR) applications.
The reference designs are very suitable for real customer metering applications, thanks to their integrated human-machine interfaces (HMI) and communication interfaces for remote data collection and automated meter reading (AMR). For a faster time to market, the designs provide both the hardware and the software sources for customer applications.
