Power Line Communication (PLC) is a communication method that uses power lines as the medium, so it is possible to build a system quickly at a low cost. Using this method, communication data can be propagated through AC or DC power lines. For example, building automation can be realized using existing AC power lines in the building. Alternatively, DC power lines can be used for communication between devices, reducing device harnesses.

Renesas provides a narrow-band PLC modem IC, R9A06G061, which enables high-speed communication over 1Mbps and stable long-distance communication over 1km for peer-to-peer networks.

System Benefits​:

  • The PLC unit can be configured using Renesas products, including the R9A06G061 PLC modem, line driver, and AC/DC and DC/DC regulators. For a DC line, the PLC unit can be configured in a small size of about 3cm square. The PLC unit actual schematics, BOM lists and Gerber data are also ready.
  • Evaluation boards optimized for AC lines and DC lines are available. A "Performance Test Tool" and sample application software are available which run on the evaluation board. Customers can immediately develop and evaluate a PLC system. Renesas also prepares board schematics, BOM lists and PCB layout guides to support customer development.
