EMI and EMC considerations for energy meters
It is a joint responsibility of microcontroller designers and PCB designers to provide protection within the metering system, so that the meters are not affected by a noisy environment.
Freescale introduced the MKM34 series of microcontrollers for the single-phase and three-phase metering markets. This series of microcontrollers has a higher immunity against electrostatic discharge (ESD) and high-frequency noise tampers. The MKM34 series of devices produce good results when integrated within a good PCB design.
