microcontroller suggestions for a new STM32 project ?

[gianlucamilani]

I’m choosing a microcontroller for a new STM32 design and I’d appreciate some recommendations.
I don’t have particular requirements for compute performance, memory size, or ultra‑low power — just solid peripheral support and a Nucleo board available for development.

Required peripherals:

• 1 × FDCAN (CAN FD)

• 3 × SPI (in practice only 1 SPI with multiple CS likely)

• 3 × I2C 

Constraints:

• Prefer MCU in LQFP / QFN (no BGA)

• Compact (48 pins) 

• Development on a Nucleo board 

I’ve looked at parts like STM32C552VET6 and STM32L552CCT6 as potential targets, but I can’t find a dedicated Nucleo board for them.

Any suggestion?

thank you,

best regards,

I have another question. 

Which is the suggested way to start the design of the schematic for a custom board using H5 or G49 MCU in easy way? I am struggling a bit in finding documentation for quick setup and apllication examples of the hardware design and pin assignment (how to power the MCU, selecting GPIOs for communication, set up the crystal, the programming pins, etc). Do you suggest me to start with :

- MCU datasheet 

- CubeMX configurator (but there are not guidelines for power programming etc)

- NUCLEO schematic docs

- some documentation such as  AN4488 hardware guidelines (but related to H5 or G49 famililies)

- other?

thank you

Hello @gianlucamilani ,

This post is closed and you previous post that you have asked the same question was moved in a separated thread here. We've already provided answers there.

We need to separate topics in the community: one question/topic by thread.

Thank you for your understanding.
