Seeking Recommendations for Dual-Core STM32 Microcontrollers

[STbeginner]

Hello everyone,

I am currently working on a project that requires a dual-core microcontroller with the following specifications:

• Flash Memory: 256 KB to 1 MB
• RAM: 16 KB to 64 KB
• Architecture: 16-bit / 32-bit MCUs
• RTOS Support: Yes
• Clock Frequency: 48 MHz to 100 MHz
• Core: Dual core
• Over The Air programming: Yes

I would greatly appreciate your suggestions on the best STM32 models that meet these criteria. If you have experience with any specific models, please share your insights regarding their performance, ease of use, and any potential drawbacks.

Why is that ?

Dual core MCUs add significant complexity.

You can see that STM32H7 is the dual-core family

So you want a radio?

Options there are:

But they may not fit your other criteria.

Perhaps explain your actual system requirements?

As @Ozone says, why specifically dual-core? What system requirement drives that?
