High-performance multi-band wireless communication LSI "ML7436N" ideal for building wide area networks

     LAPIS Technology Co., Ltd., a subsidiary of ROHM Group, has successfully developed a multi-band wireless communication LSI "ML7436N" suitable for WAN construction. In addition to being suitable for infrastructure fields such as smart meters and smart street lights, this product can also be widely used in smart factories, smart logistics and other fields.

     In recent years, with the application and popularization of IoT devices, the fields of infrastructure, factories and logistics have shown a trend of intelligent development. In order to realize communication covering a wide area network, it is necessary to build a mesh network that ensures communication stability and high confidentiality. Therefore, the demand for wireless communication LSIs equipped with large-capacity memory and CPUs with excellent processing power is also increasing. In addition, in Japan, with the revision of relevant laws and regulations, it is required that from April 2020, all IoT devices must have their own update function, so it is necessary to be equipped with a firmware update function under remote conditions. LAPIS Technology has solved the above problems by making full use of the wireless technology that has a strong market performance in the field of smart meters, and has successfully developed new products for Mesh network construction that are convenient for global promotion and more secure.

     The new product is equipped with a 32-bit CPU core "Arm Cortex-M3" capable of high-speed operation, and a 1024KB memory, which is the highest-capacity level in the wireless communication LSI industry. The memory can support the operation of large programs such as multi-hop network (relay function) and firmware update in a wireless environment and the storage of large amounts of data. Therefore, it is conducive to the construction of a wide-area mesh network of the system and reduces maintenance work. In addition, it is also equipped with a strong encryption circuit, which can further improve the security of the system.

     So far, IoT devices used all over the world need to be developed according to the requirements of wireless-related laws, regulations and standards in various countries, and this new product is equipped with RF that supports multiple frequency bands (Sub-1GHz and 2.4GHz). chip, so it can be widely used in different countries and regions around the world.
