STM32W RF Power Management

Question asked by melcer.george on Jan 17, 2013
Hi Everyone,

I am looking to do use a STM32W chip in an application that is isolated from power and I would like to make it run for several months at a time between charging of the battery. To make matters worse, not only are we isolated from power but we have space constraints too so I can't use a car battery to keep this thing running for all eternity (though I do have dreams about that lol). 
 
Anyway...I assume I'm not the only one who has had to deal with an application like this and was wondering if anyone has tips on how to do implement a good power management routine or/and what kind of power you are drawing. To make matters worse, this device needs to turn on/of a bunch of switches in what seems like real-time (a user will control it via another device). So if I have to poll, I would need to poll ~every second--to make it appear like it is happening in real-time. 

Thank you all for reading and any assistance..
-George
