Cool Phoenix
Flexible PLC Modem Solution

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
