Hi, I want to project controller board powered by 2 AAA batteries. It should have power down-wake up functionality (for long battery life) and serial communication. Are there any low power supply versions with 8032 core or better use a high efficiency step up regulator (than I could use my 5V programming environment).
"I am sure Maxim or Linear have a simple 2.7V to 5V boost regulator that you could use if you wanted to." I'm certain they do. However, if you want to go this route, you'd probably be better to look at one of their converters that runs from a single cell. This will simplify your mechanical design, and give better overall battery utilisation. You could probably use a single AA rather than two AAAs - which gives you a better energy density anyway.
