Hello,
We are designing automotive devices (Trackets,Meters etc) and almost in all of our devices we use external watchdog with integrated BOD function.
We faced issues in the past during EMC/ESD tests, where the microcontroller's (AVR) BOD or watchdog internal circuit was frozen. We know about independent watchdog clock etc but does anyone faced watchdog/BOD issues on STM32 MCUs during tests?
What does ST recommend for the STM32Fx families?
In most of ours STM32 MCU based devices, we keep the external watchdog circuit.
