Regarding Auto grade Controller in stm32h7 series

Hello everyone, I want to work on STM32 series of controller which supports 480MHZ or above clock rate and Auto grade temperature range(I.e Grade0: -40degc to 150degc (or) Grade1:-40degc to 125degc).We found STM32H7 series which supports our applica...

Phantom external interrupt issue with STM32F469AI (custom board)

I am witnessing interrupts on EXTI9_5 line which have absolutely no electrical stimulus. I'm seeing this behavior consistently on multiple chips so this isn't a one-off.The GPIO in question (ONE_WIRE_PIN) is PA8.GPIO initialization here:mIRQConfig.Pi...
