Focus on the Internet of Things: Core Products, Core Market, Core Information
The initial impression of Xinke should be around 2014/5 at the earliest, when the SI44xx series penetrated many customers in the market. I remember that one is the feature of low power consumption, and the other is a beautiful price, about US$0.6;
Later, I also saw the promotion of Xinke in the Bluetooth and zigbee markets, and the zigbee chip became the market leader;
You may understand that it is difficult to make a processor, not only in chip design, but also in the ability and high investment of the software team. It can be seen that Silicon Labs is really good at these two aspects;
On 2/25, Xinke and the CSA Alliance jointly launched Matter's technical training, which was extremely popular. A friend told me that the number of people who just watched it exceeded 3,000. On Friday night, I couldn't wait to watch it on bilibili. There are many, and there are also many super dry goods in it, let me share with you;

01
full stack solution
I haven't looked at Silabs' product series for a while, and found that there are more members; embedded and analog are very different, that is, they need a more complete package and a soft soul; especially for network design, the requirements are higher;
As a leading chip company, Silabs is naturally top-notch in this part; here are two main pictures, one is the chip, and the other is the supporting tools and software
Seeing the chip page, there is also an interesting point, which does not include Tranceiver such as WF200 and RS9116;
In terms of software, apart from the protocol stack, Simplicity Stutio5, a graphical development & code management tool, and corresponding modules are provided; the PPT may not have enough space, and no mobile APP and debugging tools are included;
02
MultiPAN NCP & OTBR
This is a multi-protocol gateway launched by SILABS. The chip combination is WF200 (WiFi) + MG21 (Radio Co-Processor) + SSSD202d (SigmaStar's edge vision light processor, running Linux), which can support ZIGBEE network and Matter & Thread network;
Here are a few features and an interesting point:
The first feature: ZIGBEE&Matter compatible
What's the point?
At present, for many brands and solution providers, ZIGBEE's network is ready-made, which is the advantage of their years of hard work;
After Matter comes out, it needs to be upgraded in order to be compatible. Many solution providers here must hope that the original product can support my own network and be compatible with Matter, so that my original network can be guaranteed, embrace the Matter ecology, and ship products;
This is also the original intention of Matter, to reduce the number of SKUs of solution providers;
Second feature: Bluetooth low energy compatible
Bluetooth is one of the Matter network distribution channels, and it is also a common way of WiFi distribution network; Silabs' MG21 is directly compatible with 802.15.4 and BLE, which meets the distribution network requirements and reduces the cost of the entire solution;
Silabs also specifically mentioned that in order not to affect the ZIGBEE/Thread network, the application of BLE should be reduced; well, whoever makes it compatible knows the pain...
Interesting point: choose the SigmaStar chip as the Host
I'm actually thinking about what kind of chip can be used as the main control of Matter gateway. From a technical point of view, I personally understand why Silabs chooses SSD202; maybe wireless friends don't know about this chip. This is a support edge processor for vision and light ISP;
There may be a hypothesis here. In the follow-up network, the gateway will not be just a gateway. It can be a speaker, a door lock, or a camera. If this assumption is true, it is easy to understand the advantages of similar chips like SSD202;
03
Matter who contributes the most
A very interesting picture. I always thought that Google was the most active contributor. Silabs showed a picture based on the amount of submitted code. Here, Apple is the biggest contributor; in addition, Amazon contributes about 5%;
Silabs is also great in order to eat the benefits of matter, ranking third; everyone may have their own opinions behind the data;
04
test network
Those who work on the Internet know the hardships of testing. The development students have been iterating and iterating, and the testing students are happy; of course, the testing masters don’t worry about this problem;
Silabs is obviously a master in testing. This training also shows some information about Silabs in testing hardware, test scenarios, and automated testing tools;
This is the test tool and test scenario. One site includes 6 nodes; then there are 25 sites in the office space, so that the network performance of 150 nodes can be verified and tested in the actual environment;
This is a small network for CI testing. After the code is developed and submitted, the test is automatically triggered, and the test students can sleep on weekends;
05
Matter's Roadmap
A very interesting piece of information, Silabs made a simple arrangement of Matter's Test Event process, and gave its own plan roadmap, save the show muscles;
Matter is currently preparing the 0.8 version of the test internally. If it passes, it will be ready to enter the release process; the release time is expected to be in May-June of this year;

Training review address
You can search for SiliconLabs in bilibili, and there is a review of the entire training content, which is highly recommended;
Study Matter's attention official account, there will be other good content in the near future~~
