Protection circuit for using the micro controller for industrial application

[NGopa.1]

Hi Friends,

Hope all are safe and doing well in this situation.

I want to use the STM32 Micro controllers for industrial purpose. In such case what is the protection circuits that i need to be used to withstand the controller from ESD and other scenrios. Is there any sample circuits or technical guide lines please share friends

You'd have to decide what level of ESD protection you require and for which pins and go from there. The GPIO pins can withstand a fair amount of ESD by themselves. See datasheet for details.
