While the smart home field is booming, the smart speakers that play a central role inApple,Google,AmazonThere are many solutions from different companies, and compatibility is an issue. Therefore, what is currently attracting a great deal of attention is the new communication standard for smart home devices.Matter"am.2022Year1Digital Technology Trade Fair held in Las Vegas in MayCES 2022' was also highlighted.
Here are some things you should know when developing smart home productsMatteroverview and recommended wirelessSoCsI'd like to introduce_______
Watch video for introducing Matter
We have started on-demand distribution so that you can watch the seminar video for Matter introduction at any time.
In this video, we also explain from the aspects of "Benefits, future prospects, and challenges of introducing the Matter standard" and "Product security required to comply with Matter".

New standard for smart home connection "Matter". Compatible with smart speakers from various companies
IoTThe smart home market, which builds a comfortable life by utilizing , is heating up. The impetus wasAIIt is the spread of smart speakers that can be interactively operated by voice. By linking smart home products based on smart speakers, it is possible to operate home appliances by voice and remote control from outside.
However, smart speakers todayApple,Google,AmazonIt has been released by companies such as , and is in a state of confusion. Developers of smart home products have to deal with each company's smart speakers individually, creating compatibility challenges.
Communication standards related to smart homes have so farECHONET LiteThere is a smart home standard from Japan called ", but the current situation is that it has not spread widely.
Currently, it is expected to become a connection standard for smart homes.Matterteeth,Apple,Google,AmazonA standardization organization in which many companies participate, includingConnectivity Standards Alliance(CSA)” is promoted by Since companies with a large market share in smart speakers are participating, in the future smart home relatedMatteris expected to become the standard.
“Matter” Usage Scenarios and Issues in Smart Home Product Development
Matteris expected to be used for the following smart home products in general.
<Usage example>
・Smart lighting (voice control, remote control)
・Smart TV (voice control, remote control)
・Smart curtains (voice control, remote control, automatic opening and closing)
・Smart air conditioner (voice control, remote control, automatic on/off)
・Smart lock (locking and unlocking with a smartphone)
・Smart garage door opener (remote monitoring of door opening/closing)
・Security sensors (window opening/closing monitoring, confirmation of presence of people and animals, etc.)
・Smart plug (device current consumption monitoring, power on/off)
In the past, the following points were issues in the development of smart home products.
Issue (1) Response to each company's smart speaker
Until now, there was no unified standard, but in the futureMatteris expected to become the standard. smart home devicesMatterBy developing compatible with , there is no need to individually support each company's smart speaker, and development can be labor-saving. Buyer in the futureMatterSince you only need to check whether it is compatible withMatterNon-compliant smart home devices are likely to be eliminated from the market.
Issue (2) Response to edge computing
The functions of smart home devices are becoming more sophisticated,AIThere is a growing demand for high-precision detection and judgment in real time. Therefore, the terminal itself such as sensor, microphone, camera, etc.AIThe importance of edge computing to implement For the parts to be incorporated,AISpecs that can handle processing are now required.
Issue (3) Reduction of power consumption
In the smart home area, there are many devices that run on batteries, and reducing power consumption is a major issue. This is because frequent battery replacement is stressful for users when using smart homes. In particular, if power is consumed during standby, the battery will run out at the timing when it should operate, leading to a decrease in usability.
Best suited for the smart home field with top-level low power consumption. Silicon Labs Wireless SoC "MG24"
Silicon Laboratories (Silicon Lab) is one of the smart homes with such development challenges. The companyMatterformulate standardsCSAas a board member and plays a central role.
Wireless provided by the companySoCs"MG24” is multi-protocol compatible with low power consumption.AIIt is a spec suitable for mounting. Perfect for smart home productsMG24Introducing the features of
Features (1) Top-level low power consumption
MG24 is based on Silicon Labs' proprietary technology "PRS(Peripheral Reflex System)" achieves top-level low power consumption. In addition to the normal bus, triggers are set for all peripheral blocks, making it possible for peripherals to work together and process information even when the core sleeps. Since the operation of the microcomputer can be suppressed, power consumption can be reduced.
Features (2) Built-in AI accelerator
It has a built-in Matrix Vector Processorsuitable for AI and machine learningseparately from the main microcomputer, and has the performance to support edge computing without imposing a heavy load on the main microcomputer.
Feature (3) High RF reception sensitivity
In order to realize a stress-free smart home environment, it is necessary for the terminal to be connected to the network stably.The MG24has high RFreception sensitivity and wide network coverage.
