Power Line Communication (PLC) is a rapidly growing market. Utilizing Renesas’ third generation of market-leading powerline communication modem solutions, this winning combination illustrates how PLC can be used in an IoT application. In this design, the RL78/I1C MCU is utilized to measure the voltage/current/phase of the AC power line. That data is then transmitted over PLC via the RL78/G13 to the CPX3 modem SoC. These devices are powered by the ISL85415 step-down regulator and a Renesas photocoupler is also utilized to detect zero-crossings and to protect the CPX3 from potential voltage spikes.
