Inquiry Regarding Development Options for STM32C091CBT6

[Kadir]

Hi,

I am currently working with the STM32C091CBT6 microcontroller and am looking for suitable development hardware.

My primary questions are:

1. Is there an official STM32 Discovery kit or Nucleo board specifically designed for the STM32C091CBT6 microcontroller? If so, could you please provide the part number or a link to its product page?

1. If a dedicated development board for the STM32C091CBT6 is not available, what is the recommended approach for using the NUCLEO-C092RC board with the STM32C091CBT6 microcontroller? Specifically, I am interested in understanding: * Are the pinouts compatible enough for direct connection or would an adapter be necessary? 

Thank you for your time and assistance with this matter. I look forward to your guidance.

BR,

They are not the same package. One is a LQFP48 and the nucleo board chip is a LQFP64, so the pinouts will not be compatible.

There are relatively few differences in the MCU apart from the pinout, so it would be possible to use the nucleo board for development, restricting yourself to only using pins available on the LQFP48, and copy the code over to the new MCU when the time is right. Perhaps also restrict your usage of RAM to the lesser of the two chips.
