Compatibility for STM32L4P5CET6 ?
Posted: Wed Mar 23, 2022 5:39 pm
Howdy folks -
I'm a bit new to this.... Sorry.
I just finished a nasty little reverse engineering job on an AliExpress VR display driver board featuring the steadfast STM32F103C8T6, sometimes, or one of the clones. It was a terrible slog, but I got it, just in time to realize that perhaps, I could use a bit more program FLASH. Right now I'm at 91% full, no bootloader, and I want to be able to put serial numbers on the boards that I can read out later without having to resort to hard-coding ones in every time I compile. I know there's a 128KB version of this chip which is the obvious choice, but of course, they're impossible to buy, and what's more, some of the boards that I have feature clone CPUs which is not ideal, plus I'm not sure if pulling unique IDs from clones is even possible.
but I DO have a small number of STM32L4P5CET6 available, and they look pin-for-pin compatible. In the process of decoding this board I've reworked these original chips on and off the board several times, and have no qualms re-chipping them.
I don't see this particular chip in any of the lists. Is there some resource that I can look in to that would help me identify family compatibility / compile / core options for this chip? If there even are any? Am I mistaken that they're pin compatible?
Thanks team, and sorry for the nOOb questions.
