LAPIS Semiconductor, a subsidiary of the ROHM Group, has developed a wireless communication LSI "ML7406" that conforms to the 868MHz European smart meter communication standard Wireless M-bus Note 1. The product is equipped with the signal processing function of each mode required by the Wireless M-bus standard according to the specification, thereby reducing the microcontroller load by about 20%, successfully reducing the overall power consumption of the device, and is very helpful for battery drive Long-term driving of similar smart meters and reduced maintenance.
In addition, LAPIS Semiconductor has developed the "ML7344E" that complies with the Wireless M-bus standard at 169MHz (N-Mode) and 433MHz (F-Mode). This time through the development of "ML7406" for 868MHz, ROHM has a lineup of products covering the entire frequency band of Wireless M-bus, which can meet the needs of smart meter markets in European countries.
Samples of this product have been sold since April, and mass production and sales are expected to begin in September. The production base for the early stage is LAPIS Semiconductor Miyagi Co., Ltd. (Miyagi Prefecture, Japan), and the production base for the later stage is LAPIS Semiconductor Miyazaki Co., Ltd. (Miyazaki Prefecture, Japan).
In addition, "ML7406" is suitable for the 750MHz ~ 960MHz frequency band, not only conforms to the ARIB STD-T108 Note 2 standard in Japan, but also conforms to the world standard IEEE802.15.4g. EMS) and other broad fields.
In recent years, countries around the world have begun to work on the development of smart meters. In Europe, it is generally believed that the Wireless M-bus method will become the mainstream data communication method. The Wireless M-bus in the 868MHz band, which is expected to be popularized in Germany and its neighboring countries, has three modes. It is necessary to distinguish signals according to different modes according to the operation mode. Traditionally, the software on the microcontroller side performs packet processing to discern patterns and information, which puts a heavy load on the microcontroller and leads to increased power consumption.
LAPIS Semiconductor is a major member of the OMS (Open Metering System) Note 3 protocol development working on Wireless M-bus. In addition, Steinbeis, a large supplier of the protocol, has jointly developed product specifications related to the hardware processing of packet processing. Therefore, the Wireless M-bus packet processing program is built into this LSI. The Wireless M-bus packet processing program can handle the simultaneous standby function of C mode and T mode through hardware, the automatic discrimination function of Format-A and Format-B information in C mode, and automatically determine whether the local packet or other data Packet address filtering function, etc. Through these efforts, the operating rate of the microcontroller can be reduced by about 20% compared with the previous system that is processed by software, which is very helpful to reduce the power consumption of the device.
Not only that, the protocol stack for Wireless M-bus can provide sample software and C source code with built-in T-mode, C-mode, and S-mode functions that comply with EN113757-4: 2011. In addition, the OMS protocol stack and Wireless M-bus protocol analysis software that can be directly used in OMS-type instrument products can also be licensed from Steinbeis.

? Automatic Wake Up, automatic sleep function, high-speed radio wave detection function
Using the 32kHz internal RC oscillator or external clock input to control the internal timer, the LSI can repeat the periodic operation from the sleep mode to the reception mode or the transmission mode, and then return to the sleep mode without a microcontroller command. Combined with the high-speed radio wave detection function, it periodically detects the presence or absence of radio waves in the shortest time. When it is judged that there is no radio wave, it can resume the sleep state.

Products involve multiple fields, including ICs, discrete components, optical components, passive components, modules, semiconductor applications, and medical appliances. In the world's electronics industry, Roma's many high-quality products have received market approval and praise, becoming the leading enterprise in system IC and the latest semiconductor technology.
ROHM attaches great importance to the Chinese market. It has successively set up a number of representative offices across the country, opened factories in Dalian and Tianjin, and set up design centers and quality assurance centers in Shanghai and Shenzhen to provide technical and quality support.
[About the development of ROHM's business in China]
As the sales outlet in the Chinese market, ROHM Semiconductor Hong Kong Co., Ltd. was established as early as 1974. Subsequently, Roma Semiconductor (Shanghai) Co., Ltd. was established in 1999, Roma Semiconductor Trading (Dalian) Co., Ltd. was established in 2003, and Roma Semiconductor (Shenzhen) Co., Ltd. was established in 2006. In order to quickly and accurately respond to the requirements of the expanding Chinese market, ROHM has established a one-stop system in China that integrates development, sales, and manufacturing with ROHM Japan. As a characteristic of Roma, we actively carry out "close to customers" sales activities, and strive to provide customers with thoughtful services. Since the establishment of five inland regions such as Xi'an, Chengdu, Chongqing, Wuhan, and Changchun since the second half of 2010, there are currently 22 sales outlets nationwide, including Hong Kong, Shanghai, Dalian, and Shenzhen Sales company and its 18 branches (branch: Beijing, Tianjin, Qingdao, Changchun, Nanjing, Wuxi, Suzhou, Hangzhou, Ningbo, Xi'an, Wuhan, Dongguan, Guangzhou, Huizhou, Xiamen, Zhuhai, Chengdu, Chongqing). And, it is gradually expanding its distribution network.
As a technology base, it has design centers and QA centers in Shanghai and Shenzhen to provide technical and quality support. The design center is equipped with development and design support personnel who are proficient in various markets, and can make technical proposals in accordance with customer needs in the form of comprehensive solutions from software to hardware. And, when the product has a bad situation, the QA center will reply to the appeal within 24 hours. As production bases, production plants were established in Tianjin (Rohm Semiconductor (China) Co., Ltd.) and Dalian (Rohm Electronics Dalian Co., Ltd.) in 1993. Production of diodes, LEDs, laser diodes, LED displays, light sensors in Tianjin, power modules, thermal print heads, contact image sensor heads, picture link modules, LED lighting modules, light sensors, LED displays in Dalian Production, as Roma's main production base, continuously provides high-quality products to China and abroad.
In addition, as a part of social contribution activities, Roma is also committed to strengthening cooperation with many domestic and foreign research institutions and enterprises, and actively promoting joint research and development activities of industry, university and research institutes. In 2006, Tsinghua University signed an industry-university joint framework agreement, and actively launched the industry-university cooperation on the development of the most cutting-edge technology of electronic components. In 2008, it donated money to build the "Tsinghua Roma Electronic Engineering Museum" in Tsinghua University, and it was completed in April 2011. In 2012, the "Tsinghua-Rome Joint Research Center" was established at Tsinghua University to engage in joint research projects such as "microenergy devices, silicon luminophores, biosensors, and China's digital broadcasting (demodulators)". In addition to Tsinghua University, Roma has also carried out industrial-academic cooperation with universities such as Xi'an Jiaotong University, University of Electronic Science and Technology, Zhejiang University and Tongji University, and has continuously produced fruitful results.
