• DRM143, Kinetis-M One-Phase Power Meter Reference Design. The electro-mechanical power meter has been gradually replaced by the electronic meter. Modern electronic meters have a number of advantages over their electro-mechanical predecessors. Their mechanical construction is more cost-effective due to the fact that there are no moving parts. This design reference manual describes a solution for a one-phase electronic power meter based on the MKM34Z128CLL5 microcontroller. This microcontroller is part of the Kinetis-M microcontroller family. The Kinetis-M microcontrollers address accuracy needs by providing a high-performance analog front-end (24-bit AFE) combined with an embedded Programmable Gain Amplifier (PGA)
