Looking for a low power consumption processor

I am looking for a small microcontroller that can handle four interrupts coming into it. It also needs to be on all the time so I need a low power consumption. It also needs to take up a small space so it needs to be a qfn or similar device.

perhaps like 296-41329-1-ND there is many options perhaps you have a power consumption you need to meet and or a physical size you need to not go over ?

Thanks, that was helpful. I would like to get the current down from 370 uA. How do you know it can handle the interrupts. Is the timer on the pins what I need to search for?
