hello!
accidentally found some very cheap microcontrollers in china.
A clone of the classic 51:
integrated bootloader, usb support, accelerated version. Minimal changes in register bits.
Has anyone tried these products? i'm very curious!

Yes, I have.
What do you need to know?
The manufacturer is quite well known for making improved copies of the STM32.
I'm just afraid we won't understand each other linguistically.

google or other message translation software can help us: www.deepl.com/translator

it has not been a problem for the last 5-8 years.
I communicate with people from different countries: Poles, Bulgarians, Serbs, Germans, Dutch, Americans and Chinese.

Hello,
Chinese-only manual and run it through the translator.
The links I send are in multiple versions. Yes uses USB. There is already an implementation of so kernel arduina. I send links for study.
I don't know what you're hoping for, I got it tested and found out it worked, but the manufacturer's support is practically none put it off, but if you insist on the 8051 core you'll look at the silabs.
He has more support and is in a normal language for us. I don't want to offend my fellow Japanese who is here, but for us Europeans it's indecipherable. Smile
Promised links

is a good warning. Yes, it is more reliable to use products from reputable companies!
I wanted to buy some of these products just because of interest. For my work the AVR is enough

Hi

These chips are also produced.
http://www.stcmicro.com/stc/stc51.html
Support is better drivers are also in Keil. And they have manuals in English.
There was one company, but I can't find samples and notes. But I suppose these clones Mark will never add so translators.
I can't imagine what would be good these days. The silabs on the other side are still making them, so I guess there will be an outlet.
So if you want to play, go ahead. If I hadn't been called in for tests, I wouldn't be playing.

Hi
I knew there was another company that makes "clones" of the 8051.
Coincidentally I have now been commissioned to test one product and there is an IO N76E003AT20 used. Which is an alternative (almost to the 89C4052) with more memory etc. It is made, like many other "aperture" products, by Nuvoton. The price is also interesting.
https://direct.nuvoton.com/en/8051-all-series/
Just for info if you ever get bored and want to play around.
It is used in this product for example

hi
Yes, I know about Nuvoton: they are developing clones of various uC families.
Thank you.

(Dziękuję Ci!)
