That's why I think the converter might be useful. As you have already pointed out in your comment, reducing the frequency actually enables the chip to run on much lower voltage so this could be an alternative way to go. Though you can not rely on reference voltage any more if it is not regulated, but this is another story. | |

| Jan 24, 2015 at 18:03 | comment | added | Robert Špendl | I beg to differ. A step-up converter assures the microcontroller to work until the very end of battery capacity and enables reporting low-battery status. Assuming the battery is providing accurate voltage is energy efficient (about 15% more efficient) but far from reliable. | |
