An application note from Microchip: Lowering power consumption on PIC microcontrollers
Low-power applications represent a significant portion of the future market for embedded systems. Every year, more designers are required to make designs portable, wireless and energy efficient. This document seeks to simplify the transition to low-power applications by providing a single location for the foundations of low-power design for embedded systems. The examples discussed in this document will focus on power consumption from the viewpoint of the microcontroller (MCU). As the brain of the application, the MCU typically consumes the most power and has the most control over the system power consumption.
Thanks for pointing this out
Well worth a read it your designing battery powered stuff, looks a bit heavy but was quite easy to read really (though I had to go back to my Art of Electronics book to remember what maximise impedance in current paths actually meant!).
Found a couple of good tips and jogged my memory for a few things I forgot, best of all it is general enough for any MCU not just PIC. I may have to re-design my mobile terminal with my new knowledge to see if I can squeeze a bit more battery life out of it :-)
I had a kind of “deja vu” feeling

Anyway, it is a “must to ” read application note :)
