Most of these sorts of high-end microcontrollers are fully static (no clock necessary) and can shut down just the core or the core and the clock oscillator - giving you microamp supply currents. > How fast are these StrongARM chips? At least high-end 486. >I also have a *BSD bias built into me, There is a NetBSD port for the StrongARM - I've seen it running (many years ago). You might also try talking to AMSAT. They've got a fair amount of experience building space-rated hardware on a shoe-string.
