Hello,
I would like my STM32 to be able to wake up from sleep / standby by an interrupt caused by input on an analog pin passing a certain threshold (let's say, 2V).
Is this an existing capability?
How is it called? is there a way to look for this capability in tools, such as ST MCU Finder?
Thanks!

Yes.. Try to search for MCU with compararator (COMP) capability.
Inverted or/ and non inverted comparator's inputs can be assigned to pins, internal ref voltages, DAC outputs and can generate interrupts with configurable triggering.
