Hello,

I am ready to use STM32C531 in project. Right now, I am using Keil MDK V5.29 and it does not support this micro. Can anybody 

help to tell me which Keil version support this micro? If I do not use Keil, does any other IDE/Compiler support this micro develop? 

 

Thanks,

As the datasheet is from April ‘26, the device seems relatively new.

Why not asking Keil if they plan to support it, and when ?
Nor sure if you are a commercial user or hobbyist, but Keil has a well-kept user forum themselves, where you might ask as well.
Changing the toolchain inevitable causes a learning curve and additional delays.

Hello ​@Caster and welcome to the ST community,

You need to download and install the “STM32C5 Series Device Family Pack” from Keil website:
