Nessum Communication IC

Nessum* is the latest solution for IoT communications.
For wired communication, Nessum leverages the installed infrastructure through its support for various types of cables, such as powerline, coaxial, flat and twisted pair. 

Additionally, Nessum excels short-range wireless data transmission, both in air and water environments.

Nessum features reliable data transmission and intelligent device management tailored for smart city, residential, commercial and industrial applications. The SC1320A IC incorporates Nessum technologies, efficient and cost-effective IoT applications.

Nessum is the former HD-PLC Solution/Alliance that evolved to a new stage since it is used beyond the power line communication bridging the IoT Gap.


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.
