PLC (Power Line Communication) is attracting increasing interest as a communication technology for use in applications where low power remote monitoring or control is required. Emerging applications include street lighting, smart metering and intelligent home applications.
The M16C/6S MCU from Renesas combines on a single chip a PLC modem circuit (YITRAN IT800) that delivers excellent performance in noisy environments, a 16-bit CPU (M16C core), and peripheral I/O functions. The IT800 PLC modem circuit built into the M16C/6S is used as the base technology for the HomePlug Command and Control standard. The available development tools include a PLC evaluation board and a software library incorporating a data link layer and network layer. These provide support for PLC development.
