Baseband IC Compliant with HD-PLC Inside

Paul Boughton

ROHM has recently begun development of the industry’s first baseband IC compliant with HD PLC Inside, a newly-developed embedded broadband high-speed power line communication technology designed for home appliances, BEMS, HEMS, and HAN applications that makes it possible to configure home networks using existing power lines.

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 (ie, ACs, refrigerators), HEMS, BEMS, 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 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.

Key features include:

* Built-in ARM Core built in reduces design load significantly
The integrated 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.
* Low power consumption. Intermittent operation function is built in, cutting power consumption by up to 30 times during standby (wait) compared with convention PLC solutions.
