drop in replacement for STM32L433.

Scott Dev · ‎2021-02-26

Hi

I am using a STM32L433 100 pin and require more memory as using a display. I have looked at the STM32L452VET6 100pin , and looks identical apart from having more memory. I only use the HAL for initialisation and USB interface. Looking at the HAL files it says for the STM32L4xx, does this mean the same files can be used? And all I have to do is change the memory size in the linker file?

Best Regards

Scott

STM32CubeMX will show compatible ICs

Previous info from support was:

STM32ssyz will be compatible if ss is same (i.e. L4), and only features in both are used (if one has more UART or Memory then can use it if want compatible with other)
Even more compatible if z is same (i.e. STM32L4x6 == STM32L476==STM32L4A6), except there is different in boot pin.
Using STM32MX with desired features configured will show which chips are compatible, and use can choose "how compatible" in the search (can't remember exact button, believe is near top centre).
You should be able to switch to one with more memory, but check things like boot pin.
