For a long-term (6 months++ development, 1yr++ testing) graduate-level project, I am trying to choose a microcontroller to replace a PIC18-based system so that we can run linux.
My requirements are really only that it can run Linux 2.6+ (not a uCLinux or any linux derivative, want broadest support) and has a power footprint of less than a quarter watt when 'active'. I am not planning on doing any kind of multimedia type work, so I have no need for extra features involving LCDs, audio, or video, but I know I won't be able to find a microcontroller in this area without that kind of stuff; I just want to emphasize that my requirements are not very strict outside of power thanks for the flexibility Linux provides. It's preferred that it comes in some kind of "stamp" or single board computer (i.e. a development board), but most of these chips seem to come in at least the latter.
My current favorite option is the Atmel AP7000 (http://www.atmel.com/products/avr32/ap7/ap7_5.asp), thanks to the low power and support from the "AVR-Freaks" community. I am not really sure where to look, I just happened to stumble upon this and it had a lot less power consumption than anything else I'd seen thus far.
I have tried looking into ARM-based microcontrollers, but there are just so many choices it's very difficult to know where to look, so I was hoping to get some first (or second) hand advice about making this decision.
Any help is appreciated!
