ShanghaiNovember 24, 2022/ PR Newswire /-A few days ago, the BK7231 and BK7235 series chips of Broadcom Ltd Integrated Circuit (Shanghai) Co., Ltd. (603068.SH) first passed the Matter certification of the CSA Alliance (Connectivity Standards Alliance), becoming the first manufacturers in the world to pass the Matter certification. At the same time, BK7231 and BK7235 are also chip products certified by Wi-Fi Alliance, so Broadcom Ltd Integration is one of the first enterprises in the world to own Matter and Wi-Fi Alliance double certification chip products. Through comprehensive technology accumulation and rich product portfolio, Broadcom Ltd Integration will continue to work together to promote the construction of the AIoT ecosystem and empower the Internet of things in the new era.
Overview of Matter Protocol
With the arrival of the era of the Internet of everything, many foreign giants and domestic brand manufacturers have competed for the Central Plains and established their own intelligent ecosystem. However, the different platform agreements between brands and the lack of unified connection standards have been a difficult problem for the development of AIoT industry for a long time. If consumers buy smart home products of different brands, it is difficult to realize the interconnection between different brands; moreover, consumers often need to download and install different app according to different brands to operate, which affects the user experience of consumer application networking and brings challenges to the integrated development of the smart Internet market. Therefore, both the industry and users need a general standard that can break through the equipment connection barriers of different brands to solve the standardization problem of the interconnection agreement between different brands.
With the introduction of the Matter agreement, this dilemma is expected to be completely changed.
Matter protocol is a brand-new standard issued by CSA connection Standards Alliance (Connectivity Standards Alliance) (former Zigbee Alliance), and it is also a global standard of Internet of things based on IP. Its goal is to "break down barriers between platforms". As an application layer protocol developed to solve the interoperability of smart home devices, Matter protocol establishes a complete and unified standard for connecting compatible devices and systems. With the support of the Matter protocol, users, whether they are fans of Apple Home, Google Home, Amazon.Com Inc Alexa or Samsung SmartThings, can eliminate connection barriers when using smart devices. The launch of Matter protocol is a milestone for the development of the whole Internet of things industry.
Characteristics of Matter protocol
As a global open protocol, Matter 1.0 standard involves many complex links, such as protocol compatibility, object model definition, equipment interoperability adaptation and so on, which need the participation of many industrial chain nodes from chip to system to terminal equipment. Therefore, on the one hand, we need to take into account the existing ecology and characteristics of many smart home platform giants, including Amazon.Com Inc, Alphabet Inc-CL C, Apple Inc, etc., on the other hand, we also need to meet the security challenges brought by higher openness, as well as the need to meet the requirements for the downward compatibility of a large number of previously deployed Internet of things devices.
According to the above application requirements, Matter protocol adopts "general application layer + object model", which can be compatible with a variety of network layer transmission protocols, making it easier to configure and operate; and by using 128-bit AES-CBC 's AES-128-CCM encryption algorithm in the architecture, it can maximize the authenticity of users connected to devices in the home network and ensure the security of users' network connection.
In addition, the Matter agreement requires less resource overhead, only MCU-level computing power, and no more than 128KB RAM and no more than 1MB Flash memory space, which can help smart home products to enter the market with more cost-effective advantages, and provide users with simpler, better experience, more reliable and more secure smart life services.
Application scope of Matter protocol
The initial version of the Matter protocol supports Ethernet, Wi-Fi, low-power Bluetooth and Thread devices. Devices can be added to the Matter network through Bluetooth, interconnected through a star network formed by Wi-Fi (or Mesh network formed by Thread), and connected to devices of other protocols through a bridge. The initial version of the Matter protocol supports a variety of commonly used smart home product categories, including lighting, electrical, curtains, air conditioners, sensors, door locks, video players, inter-protocol bridges, and controls that can be embedded in many different types of products.
After the release of the Matter 1.0 standard and authentication process, it will provide users with more complete and convenient intelligent application scenarios, as well as more powerful privacy and security services. At the same time, the Matter protocol will further promote the development iteration, not only adding more new functions and equipment types, but also constantly improving technical specifications, SDK and testing capabilities. With the further evolution of Matter standard, its application will not only be limited to smart home, but also can be combined with sensor technology, artificial intelligence, edge computing and other technologies, and is expected to be applied to automotive, industrial and other multi-scene wireless communication fields.
Broadcom Ltd integrated series chips are the first to passMatter 1.0 Certification
Broadcom Ltd Integrated Circuit (Shanghai) Co., Ltd. (603068.SH) is one of the earliest chip design companies in the field of AIoT in China. The company makes full use of its relevant advantages in technology, experience and ecology to actively and jointly promote the specification development, design, testing and verification of Matter protocol, so as to promote the rapid landing of Matter protocol in the global application range.
Following the launch of the world's first Wi-Fi 6 chip used in the Internet of things in early 2021, some chips such as BK7231 and BK7235 have taken the lead in passing the Matter certification of the CSA Alliance, becoming the first manufacturers in the world to pass the Matter certification. At the same time, related products have also been certified by Wi-Fi Alliance, so Broadcom Ltd Integration is the first company in the world to own Matter and Wi-Fi Alliance double certification products at the same time.
In addition, the company's series of products support Amazon MSS, so that you can enter the Amazon Alex system more safely and quickly. The related products have also obtained PSA certification, and the information security protection capability of the chip has reached the international leading level.
With the company's product and technical advantages, the company's BK7231 chip has entered the supply chain system of customers such as graffiti, Midea, Hisense and Ridersen, while BK7235 chip can be widely used in visual doorbell, intelligent door lock, central control panel and other scenes. The company's series of products have the characteristics of multi-device access, high anti-interference ability, longer communication distance and lower power consumption, which can be used in the fields of Internet of things, including smart home appliance market, UAV and aircraft model market, module market, electrical market and so on. Play a greater role.
With the development of the Internet of things industry, 5G + AICDE (AI, IoT, Cloud, Data, Edge) will further stimulate the massive application space of industrial Internet. As a bridge between various equipment systems, the introduction of Matter standards and authentication process has brought significant results for consumer user experience, product development of R & D personnel, and commercial operation and sales, thus further promoting the rapid development of the AIoT market. With its rich high-performance product portfolio, Broadcom Ltd Integration will assist the full scene landing and terminal equipment application of Matter protocol, realize the magnanimity and multi-function of terminal edge computing nodes such as automobile, home appliances, wearable, audio and video, and jointly open up a new era for the development of AIoT Internet of things industry.
