STM32F105RCT6 vs GD32F105RCT6

[EGonc.5]

Hi

Due to a shortage of STM32F105RCT6 we need to use the GD32F105RCT6. So a firmware that is running on the ST MCU needs now to run on the GD MCU. 

Does anyone know if the GD32F105RCT6 is fully compatible with the STM32F105RCT6?

Not just the pinout but also the IO Peripherals like UARTs, Timers, USB?

Will a program made for the STM32F105RCT6 run unchanged in the GD32F105RCT6?

thanks

STM32 and GD32 resemble each other very much and most programs will run. But it is up to you to checke your program yourself. Nobody else can take your responsability.

A quick search comes back with several results that say they are not identical, although they are very similar. So "compatible" will depend on how you are using it.

Can you tell me where that search can be made, so that I can ascertain the exact differences? thanks

I used Google.

This page was oddly the most informative, although it looks to have been written by AI, or perhaps badly translated.
