EMI due to High clock speed

Hi All,

Could someone please give an opinion, regarding esp32 crazy speed of 240 MHz dual core, normally in MCU world only 48 MHz, my concern is the EMI, how to use esp32 reliably with other electronics components, can anyone share some experience with it ? is there guidelines to implement esp32 safely ? does it require external watchdog ?

Thanks

We have not one, not two but three different watchdogs, in two different clock domains, so you should be fine with respect to that I guess :) Furthermore, while the internal CPU core and memory is 240MHz, the peripheral clock is in general not more than 80MHz, so the EMI emissions should be limited to that.
(Note, I'm not an EMI expert, just putting things in perspective.)
