Mobile computing is going to tinier and tinier scales, but you haven't seen a chip this small. Freescale has made the world's smallest ARM-based chip, theKinetis KL02, measuring a mind-bogglingly tiny 1.9mm by 2.2mm.It is a full microcontroller unit and that basically means it has a processor with RAM, ROM clock and I/O control units, making it a full-fledged computer.It might not be the most powerful computer you've seen with a 48MHz 32-bit processor, 4KB of RAM and 32KB of internal storage, but you should look at this from another angle - this super tiny chip is supposed to be swallowed and be inside your body.
