I am using STM32G431cbtx and enabling RCC_MCO. Since the STM32G4 supports two pins, PA8 and PG10, PA8 is being used for another function, and I am using PG10 for RCC_MCO. However, when measuring the voltage on pin PG10, it is always high. Can anyone ...

I'm working on a project with the STM32G4 MCU. I want to know the maximum temperature at which the MCU can operate at full power. What is the corresponding internal MCU temperature for that value? What does the temperature information in the above i...

WRP cho phép cấu hình các vùng bộ nhớ Flash không thể ghi vào sau khi chúng đã bị khóa. Lõi xử lý chính (Cortex-M4) chỉ có quyền truy cập và thực thi mã nguồn trong các vùng bộ nhớ được bảo vệ bởi WRP??? Điều này đúng hay sai?

That's correct. However, the RCC_MCO signal still cannot be measured on PG10 pin!

I have tested RCC_MCO on pin PA8 and it was successful. But when I tested it on PG10 (Reset Pin), it was always high

so the maximum temperature at which the MCU can operate without performance being reduced ???

Thank you for your feedback! The area protected by PCROP will not be allowed to be written or read, but only used for storing code executed by the CPU. So, it is protected from reading by what behaviors? Can external accesses, MCU instructions be exe...

Thank you for your feedback! I am currently researching the functions of Readout protection (RDP), Proprietary Code Read Out Protection (PCROP), and Write Protection (WRP) to implement them on STM32G4xx chips for our products. However, the manufactur...
