Overview

One design supporting multiple standards: The flexible PLC modem solution is based on a highly integrated narrowband modem system-on-chip (“Cool Phoenix” or CPX), integrating a MAC controller and high performance digital signal processor (DSP) for physical layer (PHY) implementation. It is combined with an embedded analogue front end (AFE) that includes an adaptive gain amplifier with automatic gain control (AGC) functions and an embedded AES128 hardware security engine. The solution offers leading communication robustness over power lines, showing unique sensitivity characteristics. Furthermore, it shows unique overall power consumption.


A single hardware design can cover multiple smart meter platforms by:

  • Pin compatibility of a wide range of scalable Renesas RX MCU families
  • Software compatibility across the Renesas RX MCU families
  • Software configurable PLC modem supporting multiple standards including PRIME and G3
