I am using an Atmel Attiny 45 as an embedded chip on a project that I’m working on. It is my understanding that once turned on, this chip cannot be turned off without disconnecting its power source. I’m using a 3 V battery and would like to know the most effective way to have it (the chip) disconnect itself from the power source. I should mention that this device may not be used for months, thus it does need to be turned off. Should I use a relay, latching switch or other device or method unknown to me? I have very limited space within which to house the circuitry. Thank you for your replies.
