STM32G0B0CE PIN 2 PIN mcu chip replacement selection

[Carlos.K]

We would need to implement Secureboot & secure FW upgrade feature in one project.

I find both STM32G0B0CE and STM32G0B1RET6 not support RNG.

But the blow link shows they both support Secureboot

X-CUBE-SBSFU - Secure boot & secure firmware update software expansion for STM32Cube - STMicroelectronics

My question:

Whether G0x0 and G0x1 could support secureboot & upgrade features?

If not, whether you have any prefer mcu chips, pin to pin compatible preferred, for our new selection?

BRs,

Hello @Carlos.K​,

Some STM32G0x1 such as STM32G0C1 embed AES and RNG, and support SBSFU features.

Thanks for reply.

Could you tell me how much memory the SFSFU boot should add for the FW application than normal FW?

I suggest you take a look at AN5056, which contains integration guidance and detailed memory mapping.
