STM32L4P5 FT pins tolerant up to 5V even if supplied power to STM is 1.8V?
I have STM32L4P5CGU6 (48 pin).Pins PB5, PB4, PB3, PA15 are used as SPI1 with another IC which has 3.3V levels.As well as PB6, PB8, PB9 as custom input GPIOs with voltage levels of 3.3V.VDD (pin #9, pin#24, #48) -> 1.8VThey all seem to work fine, howe...
