Domestic chip replacement is the general trend! Take the topic of "replacement and why to replace" of ST chips, welcome everyone to speak... [Copy link]

 

The strategy of ST chip is ambitious! It not only deepens the cooperation with universities, but also has a wide application in the domestic market! In the last year, the price of an ordinary STM32F103C8T6 has been rising wildly from a few yuan to dozens of yuan, which really subverted our understanding of it. So how to "replace" it with low cost and efficiency is the topic we want to discuss (I currently know of two domestic companies, what about you?).
1. GigaDevice's GD (http://www.gd32mcu.com/): A single-chip microcomputer developed in China. I heard that the developer is from ST. GD32 is made based on STM32 as a template. So GD32 and STM32 are the same in many places (including the order of discipline), but GD32 is a different product after all. It is impossible for everything to use STM32. Some self-developed things are still different.
2. Hangshun HK (http://www.hsxp-hk.com/index.html): Basically, it can be said on the official website that it is compatible, but only a small part of the content has been modified.

>>>>>Advantages of domestic replacement chips are low prices.
>>>>>Some people have said about replacement. Is the program easy to transplant? Is the chip stable? I can only say that you need to experience it yourself. Domestic replacement chips are definitely the general trend. As for who will win in the end, it depends on performance, service, and maturity (data and application base).
>>>>>The above is only my personal opinion. If you have different opinions and better replacement platforms, you can speak freely!

The current method is to buy an official ST or Zhengdian Atom development board, replace the pintopin chip with it, and run the original core board process to test the stability.

What platforms have you tried? I look forward to sharing more details.

Have you tested it? Which chips did you test? How did you feel?

A few dozen bucks? Damn. Atmel is back.

Will the pricing of domestic products gradually become similar to that of ST products?

不得不說，STM的F103系列芯片是現象級的
因為一般MCU芯片的供貨週期是10年，主要型號也只有15年，參考NXP網站
作為STM原廠來說，對於F103系列的替代也早有計劃，
並且在多年前就開始實施，那就是G系列，但是畢竟沒有G1系列
原廠對於F103的價格本身上漲多少，至今沒有找到非常權威的說法
國內炒家把價格炒上去倒是真的

"The current solution is to buy ST official or Zhengdian Atom development board,"

Through the development board of Zhengdian Atom

Will this really solve the problem?

It's crazy. ST's current design is not recommended.

Another key point is that people in the country are all speculating and making money from the national crisis.

The chip market is in chaos. The prices of other chips are all out of whack.

Therefore, the safest way is to use ST as the original board and not change the PCB.

Guaranteed not to modify the PCB!!!
