Would the NUCLEO-L4R5ZI-P be the same code for STM32L4S5ZI

Hello,

I just wanted to ask if I bought the  NUCLEO-L4R5ZI-P devlopment kit before implementing the STM32L4S5ZI into my PCB. Will it still work with the same code?

Thank you

Hanya

Hello @HAhme.1​ ,

The STM32L4S5ZITx device embed an AES and a HASH hardware accelerator (compared to STM32L4RSZI). So, make sure to use the same features compatible.

Also, you need to check the pins to use, as you can see in the below screenshots, there is a difference in the pinout and the hardware need change.

I also advise you to have a look at the products Datasheets for more details and comparaison between the devices.

You can use the ST-MCU-FINDER tool (integrated also in STM32CubeMX) to compare the characteristics of two or more MCUs through the "Cross Selector" tab (see attached Excel file).

Hope my answer helped you! :smiling_face_with_smiling_eyes:

Identical code should work as long as you're using features compatible with both. Not too much different between the two.
