Rohm pre-announces HD-PLC device for smart home

New Products |
By eeNews Europe


This new standard incorporates intermittent operation functionality for significantly reduced power consumption compared with existing PLC devices.

Besides HD-PLC Inside baseband processing functionality, an ARM7TDMI core will be included for handling TCP/IP and other protocols, minimizing the amount of modifications required to existing systems, reducing development load significantly – particularly for customers new to HD-PLC technology.

Embedding HD-PLC-Inside-compliant products into home appliances, Home Energy Management Systems (HEMS), Building Energy Management Systems (BEMS), Home Access Networks (HAN), and lighting devices enables low-cost, low-power, high-speed communication over existing power lines by simply plugging into AC outlets, providing unprecedented convenience and functionality – without the need to create a new network.

Recent years has seen increased adoption of smart grid systems such as HEMS, BEMS, and HANs that connect multiple home appliances and devices and enable remote operation, energy management, and other functions that promote greater efficiency and convenience.

In 2012 Rohm joined the HD-PLC Alliance, and recently began development of an HD-PLC Inside compliant baseband IC utilizing a number of proprietary Rohm Group technologies.

Samples of the chip can be expected in March 2014, OEM quantities starting June 2014.

Key Features include a built-in ARM core and very low power consumption. The ARM core, an ARM7TDMI is designed to handle protocol (TCP/IP) processing, making it possible to incorporate into existing systems with little to no modifications. This reduces design load considerably for customers new to HD-PLC technology. Support for the ECHONET Lite middleware Smart Home communication standard and SSL encryption are also provided.

Intermittent operation function is built in, cutting power consumption by up to 30 times during standby (wait) compared with convention PLC solutions.

Rohm will present its latest developments at European Utility Week in Amsterdam, (Oct. 15 – 17, Booth 1.D07).
