Is STM32L431KBU6 available in 5V supply? We want to just changed existing part with 5V so that can avoid level shifting of SPI signals(Work on 5V).

Hi @Andrew Neil ,

Do you still have the issue with "MCU portfolio and selection" please?

There is no such issue on my side.

@Amel NASRI - seems to be OK now.

@NDesh.2 - did it work for you?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Issue resolved. we have used Buffer IC to level shift the voltage levels so continuing with same uC.
