- keithnz 7y agonot as simple either, you still need to detect that the power is gone or fading independent of the capacitor...which all adds up

- kabdib 7y agoYeah, paying thirty cents for a capacitor to coddle a ten-cent MCU doesn't make a bunch of sense. Much cheaper to teach your software folks how to write transactional updates to that flash. Typically you pay a small speed penalty to get update atomicity (in addition to having a more complicated implementation).
