DRM147, Kinetis-M Three-Phase Power Meter Reference Design. This design reference describes a solution for a three-phase electronic power meter based on the MKM34Z128CLL5 microcontroller. This microcontroller is part of the Freescale Kinetis-M microcontroller family. The Kinetis-M microcontrollers are especially designed for electronic power meter applications. Thus the Kinetis-M family offers a high-performance analog front-end (24-bit AFE) combined with an embedded Programmable Gain Amplifier (PGA). In addition to high-performance analog peripherals such as an auxiliary 16-bit SAR ADC, these new devices integrate memories, input-output ports, digital blocks, and a variety of communication options. Moreover, the ARM Cortex-M0+ core, with support for 32-bit math, enables fast execution of metering algorithms
