Smart-Meter-lg.jpgTwo-Phase Power Meter reference design. The Kinetis M series two-phase electricity meter reference provides a high-performance analog front end (24-bit AFE) combined with an embedded programmable gain amplifier (PGA) to increase the accuracy of energy measurement. It is used for measurement and registration of active and reactive energy in single-phase three-wire networks for direct connection and is pre-certified according to ANSI C12.20, class 0.2.




  • Integrated switched mode power supply
  • NVM memories for data logging and firmware storage
  • Xtrinsic 3-axis low-power tilt sensor and 3-axis magnetometer for electronic tamper detection
  • Built-in optical readout port (infrared) with ANSI C12.18 protocol support for hand-held terminal
  • AMR expansion header for an RF communication module (802.15.4 or HAN/NAN)
