ROHM, the world's leading semiconductor manufacturer, is the first in the world. ※ Developed the baseband IC "BU82204MWV" that meets the standard "HD-PLC" of the power line carrier communication (hereinafter referred to as "PLC").
"HD-PLC" inside is a new standard for embedding "HD-PLC", which is attracting attention as a high-speed power line carrier communication method. By embedding baseband ICs conforming to this standard into M2M, IoT, and intelligent community construction equipment, etc. The existing power line is used as a communication network.
The new product not only performs the baseband processing of "HD-PLC" inside, but also has an ARM core built in. A wide range of interfaces are available to enable protocol processing such as TCP/IP inside the IC. Therefore, it is not necessary to significantly change existing systems such as home appliances, and the development burden of importing "HD-PLC" by customers can be greatly reduced. In addition, the intermittent operation function is installed, and the power consumption is significantly reduced compared with the conventional PLC products.
The product has been sold in June 2014 (2,500 yen / piece: excluding tax), and it is planned to start mass production in September 2014 with a monthly capacity of 100,000. The production base of the previous process is the ROHM headquarters plant, and the later process is ROHM Electronics Philippines, Inc. (Philippines). In addition, an evaluation board and reference software for evaluating "HD-PLC" inside were prepared for the customer.
<background>
In recent years, energy-saving awareness has never been higher in all fields, and in order to effectively use various infrastructures, intelligent communities using monitoring and management systems have attracted attention.
The ROHM Group has been developing wireless communication applications for wireless LANs and specific low-power wireless applications from a long time ago. However, "Wireless" itself has security concerns and communication barriers caused by signal interference, and the built environment using reinforced concrete and metal frames. Disadvantages such as reduced communication quality.
In order to make up for these shortcomings, the ROHM Group has built a communication method compatible with wireless, and has been making efforts to effectively utilize the "HD-PLC" of the wired power line network. In 2012, we joined the ROHM of the "HD-PLC" alliance to realize the new standard "HD-PLC" inside, and integrated the rich technology of the group to develop a baseband IC that conforms to the "HD-PLC" inside.
<Features>
1. Equipped with TCP/IP protocol stack
The baseband IC developed this time integrates the ARM core, which not only performs the baseband processing of "HD-PLC" inside, but also carries the TCP/IP protocol processing function. In addition, the data interface with the host CPU uses the "UART" "SPI" that is best suited for embedded applications. Therefore, it is not necessary to significantly change the existing system of the accessory product, and the development burden of the customer to import the "HD-PLC" can be reduced. In addition, software customization is possible, and middleware products such as smart home communication standards ECHONET Lite and SSL (encryption) are supported.
2. Equipped with a rich interface
In addition to the "UART" and "SPI" used for the data interface with the host CPU, "I2C", "PWM" and "GPIO" for peripheral devices such as various sensors and LED components are also mounted. Simple system construction is achieved by controlling the built-in CPU.
3. Achieve low power consumption
Built-in intermittent operation function, the power consumption during data reception standby is lower, only 1/30 compared with the previous "HD-PLC" Complete standard.
<term explanation>
? "HD-PLC" (High DefiniTIon Power Line CommunicaTIon)
"HD-PLC" is a PLC standard developed by Panasonic Corporation. The theoretical maximum transmission speed can reach 200 Mbps or more. This solves the problem of PLC all the time and makes it possible to realize a home network that can transmit large-capacity video. .
This standard has not only been popularized in Japan, but has also been recognized as an IEEE 1901 "HD-PLC" by the IEEE standard-setting body, and has cooperated with many standards bodies such as CENELEC in Europe and IGRS in China, and has become increasingly popular in countries around the world.
?"HD-PLC" Complete
The standard originally advocated by the HD-PLC Alliance. Compared with "HD-PLC" inside, "HD-PLC" has lower power consumption and is mainly used for embedded applications such as home appliances; while "HD-PLC" complete has faster communication speed, mainly with PLC communication such as routers. Devices and large-capacity data processing devices are application objects.
?ECHONET Lite
The communication standard established by ECHONET CONSORTIUM for controlling home appliances and the like and controlling power consumption through the network.
Intermittent action
Unnecessary operations such as standby are omitted. In the IC, it means stopping a specific circuit action to reduce power consumption.
