Talking about 50 cents: After domestic substitution, is it really good? Continue to replace or return? [Copy link]

 

 

In the face of the general trend of shortages, engineers basically just want to get what they can get, which has provided many opportunities for domestic chips. Our front-line engineers are also trying to develop domestic chip alternatives with trepidation, doubt and hesitation.

So far, what is your mental journey like for those of you who have experienced and continue to be at the forefront of the alternative trend?
From now until September 16, forum members are welcome to post comments to discuss the following three questions:

1. Is domestic substitution attractive? Why?

2. What is your current MCU selection strategy for your project? Foreign manufacturers or domestic manufacturers? Why?

3. After both products are available , will you continue to use foreign chips or domestic chips? Why?

Forum members who follow the above 3 topics will have the opportunity to receive the following gifts prepared by Guanzi. Looking forward to the conversations of frontline engineers~

3. After all, you should choose domestic products when they are available. After all, you never know when you will be "choked" again, so you still have to look for domestic products.

1. At first glance, domestic products are indeed much cheaper than imported ones

2. Choose products that are in stock. Domestic products may not be available.

3. If the product is stable, choose one with price advantage.

I don’t use anything that has no domestic alternative or irreplaceable when designing.

Or choose cheap and easy to use

Cheap and easy to use

1. The price of domestic products is cheaper than that of imported products. 2. Domestic products are better than foreign products. 3. Domestic products will be used when available. Domestic chips are supported. Domestic products are not much worse than foreign products.

The performance and quality of domestic products are indeed not as good as others. Let's look at the price and supply stability! We have all switched to TI

I decided to choose the domestic one because I was discouraged by the price of ST microcontrollers. Although it was a bit difficult at first, I didn't feel any difference from the ST one after the problem was solved. Maybe the problem was not exposed.

Now our company uses domestically made MCUs, such as those from Huada, Qinheng, Hangxin, and Zhaoyi Innovation. The early debugging may take a little more time, but we have to be patient with domestic chip manufacturers. This is a process. Taiwanese and European and American MCUs have a 20 to 30-year development history. Although they are better than our domestic MCUs, I think domestic MCUs are OK. The functions and performance are similar to those of foreign ones, which can meet the needs of our products. I believe that as long as our engineers support and understand domestic manufacturers more, I believe that domestic MCUs will become more and more useful and mature.

Domestic MCUs are currently low in price, and their interface functions are very mature and not much different from those of foreign MCUs. The SDK is also good, and the interface directory hierarchy is based on foreign ones. It is easy for people who have used it to get started. It is just that it lacks anti-interference and low power consumption. I believe that it will completely beat foreign MCUs in a few years.

As always, we support domestic products. Now we have completely replaced the company's products with domestic ones.

It's neither good nor bad. At present, there is still a big gap between the overall environment and mature devices. For example, although Keil, IAR, GHS, etc. have supported a lot of domestic products, they still say that many devices are not supported. I hope to take this opportunity to speed up and catch up.

Basically, domestic alternatives can be found for MCUs. This wave of shortages has provided many opportunities for domestic chip replacement. For example, a few years ago, a friend asked me to help him develop a solution for Arteli MCU and provide the solution for free for promotion. Even so, the effect was not good. In the past few months, Arteli was out of stock, and there was no big difference between actual use and ST, and it was very easy to use. Before, a lot of people criticized domestic products for various problems and refused to understand, but now they all say they are very good. In recent years, everyone is afraid of the skyrocketing prices of foreign chips. Even if the supply and price return to the past, it is estimated that most of the alternatives will choose domestic ones. The AVR chip of that year was a lesson learned. It can only be said that the good days of foreign MCUs are over.

Domestic IDE is really difficult to use. Most of them have low compilation efficiency and cannot be read. The simulation is also not good.

Yes, Eclipse was modified, but it didn't want to be compatible with the larger environment. Every factory wanted to make some xx-link emulator, which made it a mess.

Which domestic wafer processing manufacturers now do not use Taiwan’s? This is very critical.

Chip manufacturing, chip design, chip application, manufacturing is still difficult!

Samsung is still the best at the moment. If their arm7 and amr9 can be restored and re-produced, the chip shortage problem can be alleviated. Who can convince Samsung?

1. Is domestic substitution attractive? Why?

The performance is comparable or even better, the price is cheap, and it’s really good.

2. What is your current MCU selection strategy for your project? Foreign manufacturers or domestic manufacturers? Why?

The main consideration is the tool chain ecosystem. If the cost allows, it is better to choose a foreign manufacturer. Domestic MCUs are very attractive in price, but there are not many supporting tools.

3. After both products are available, will you continue to use foreign chips or domestic chips? Why?

This is hard to say, it depends on various factors, price, performance, ecology, support, etc. I hope that ambitious domestic manufacturers can improve it as soon as possible, and if there is a choice, I will definitely choose domestic products.
