Hello Volt Tech Team,
Hope you’re doing well and everything is going well from your end.
We’ve one doubt regarding 32 KHz XTAL which is being applied to multiple ESP32-based designs and we’ve also used from reference design in our product.
But I would like to see what will be if we take off that XTAL like will it create any issue with any hardware or software working functionality if we remove it? I believe it’s mostly applied to RTC Sleep and Wakeup Mechanism.
So, would you please check and confirm from your end regarding real usage with dependencies if any for that XTAL?
Regards,
Sachin

Hello, It's required if you want stable (<5% drift) timekeeping in sleep modes where the 40 MHz crystal is switched off i.e. deep sleep, or if you want BT modem sleep. Thank You Julian White
