The NCN49597 is a powerful power line communication SoC combining low power Cortex M0 processor with a high precision analogue front end. Based on a dual 4800 Baud S−FSK channel technology， it offers an ideal compromise between speed and robustness for operations in a harsh environment. Pin to pin and function compatible with its predecessor， the AMIS49587， this new generation extends frequency up to Cenelec D band for use in applications such as e-metering， home automation and street lighting. Executing by default the IEC61334-5−1 PHY and MAC stack， the NCN49597 benefits for more than 10 years of field experience in eMetering and delivers innovative features such as a smart synchronisation and automatic baud rate detection. Fully reprogrammable， it also supports building automation standard or full custom protocol. The configurable GPIOs allow connecting peripherals such as LCD or metering ICs.
