Panasonic Corporation today announced that it has begun licensing the HD PLCTM 4 IP core required for the design of semiconductors with technologies and functions that comply with the IEEE 1901–2020 international standard.

As the fourth generation of the  HD-PLC series, this IP core will expand the scope of HD-PLC’s deployment beyond the traditional focus of power lines to existing metal wires, such as control lines and coaxial cables.  This new HD-PLC technology also enables higher speeds, greater distance, and less wiring for wired communications.  

This IP core enables semiconductor and peripheral equipment manufacturers to flexibly meet a range of IoT service requirements and manufacture products that respond to these needs. 

As a wide range of equipment in society becomes digitalized and connected to internet,  communication technology is becoming increasingly important.

While the development of wireless technologies such as 5G and high-speed fiber-optic internet gains pace, the use of existing metal wires plays an important role as a communication medium within the building walls and ceilings and underground facilities and equipment where wireless access is difficult. 

This IP core is a solution that can quickly meet the requirements of the era of IoT, such as higher-speed networks, enhanced security, and internet protocol networks. In addition, by integrating with wireless and other technologies, this IP core can help create optimal networks in a range of environments, from living spaces to social infrastructure. 

Using its experience and achievements with the HD-PLC 3 IP core, which is currently used  widely in the market, Panasonic will provide one-stop development support to users, along  with the licensing of this new IP core, including proposals for analog front-end circuitry—key  to the mounting of semiconductors.

Further, Panasonic will aim to expand the adoption of IoT  PLC, as a high-speed wired communication solution using this technology, to large-scale networks that cover not only living spaces but also social infrastructures such as buildings,  factories, smart cities, and smart buildings. 

This IP core will first be licensed to Socionext Inc. This will enable the supply of fourth-generation HD-PLC semiconductors with higher performance and lower energy consumption than conventional HD-PLC semiconductors. It is expected that these will then be built-in to a  range of IoT-connected devices. 

Panasonic will launch a dedicated website with more information about this technology. The  company will also co-host the global IEEE SA and HD-PLC Alliance*3 Webinar on March 18,  2021, together with these two organizations.  

Main Features 

– The standard mode communication band (250 Mbps) can be doubled or quadrupled,  allowing a 500 Mbps*4 communication speed in double mode or a maximum of 1 Gbps*4 in quadruple mode on coaxial cable or dedicated line. 

– The standard mode communication band can be compressed on two levels (half or  quarter), concentrating and extending the communication distance up to twice*5 the  distance in standard mode. 

– With the multi-hop function, it is possible to operate a wide area network of up to  1024 nodes.
