Product Overview


The world’s 1st communication IC to embed the latest Nessum core conforming to IEEE 1901-2020 (as of March 2021).

Multihop function is supported for extended distances.

The integration of Ethernet MAC (RMII) and UART/SPI interfaces makes the device easy to use in IoT applications.



Stable powerline communication is achieved by the combination of high quality analog and noise reduction techniques.

Long distance communication (up to 10km*, depending on the communication environment).

Low power consumption (around 200mW) by proprietary technology.

Compact package size.

With a compact power circuit design the PCB design and BOM costs can be optimized.* : Depends on the communication environment
