I wish to use the 48-pin version of the L5. If I buy a L5 Nucleo board can I target a 48-pin device and debug the code for the 48-pin device on the Nucleo board even though it has a 144-pin part fitted.

You did not tell us which 'L5 exactly, but luckily this is a small family and it's basically the same silicon die in all models.

If the Nucleo has all pins you need brought out, then yes, you can use it.

​Hi JW,

Thank you for the speedy reply. So if I build an image for a STM32L562CE I will be able to flash it into the L5 Nucleo board?

Obviously only the pins I have configured in the STM32L562CE will be activated in the 144-pin L5 on the Nucleo board.

Correct?

If the chip on Nucleo 'L552 or 'L562?

In the former case you won't be able to use the crypto functionality.

Also, I don't know whether the are SMPS variants of the 'L5s (P and Q suffixed part numbers); that might make some difference, too.

Other than that, it should be as you've said above.

​Awesome!

Thanks JW, you can close.

Hello,

Yes, it is possible. Just consider using 48-pin IOs.
