Use the lowest possible supply voltage, try reducing the clock speed while still performing the work as fast as possible. Disable clocking and cut supply voltage in as many areas as possible. Avoid integer divisions on ARM Cortex M0. Use a device with only the needed amount of peripherals, with just enough RAM and FLASH to perform the required work.

Soooo....basics, amiright?

It's nice to enumerate it. I'm sure a lot of people don't think about their microcontroller is having parts that can quiesce. Reducing the frequency of your clock until it meets your needs just barely, that's something probably most people don't do
