I have to say I really do not understand why it supports x8 chips only and not x16. I must miss a point.
because it's ultra-low-power. at 400mhz (800mhz DDR3) you'd be looking at only... what... 175mA? i think *finger-in-air* 32-bit DDR3 ICs @ 400mhz use around 350mA.
What I meant was 1x16, not 2x16, sorry for the misunderstanding. They insist on saying it supports 2x 8-bit wide chips and nothing else, but I cannot see why we could not use a single 16-bit wide chip (much easier to route).
