STM32G0 Minimum EXTI Pulse Width

gdbeatl · ‎2025-06-17

Hi Folks,

I'm working with an STM32G0B1MCT6. In my application I need to be able to react to pulses with a width of about 5 ns. It seems the only way I could pull this off is with the rising edge detection in the EXTI controller, or some additional external hardware.

Datasheets for other products include a tEXTIpw parameter. I don't see a spec in either the reference manual or datasheet for the G0 series though.

Help me ST - please can I have an official spec for this parameter on this series. Alternatively, do you have any recommendations for detecting short pulses without the EXTI peripheral?

Cheers!

Hello @gdbeatl and welcome to the ST community,

I will ask internally if we have the value of that parameter.
