How does a 1mm x 1mm chip actually get used? I'm guessing that the actual package would have to be much bigger to enable mounting on a board?

- jws 15y agoGenerally the package is big enough to get all the connections out at a scale that won't irritate manufacturing. There are tiny packages though, NXP (one of the ARM builders) has a 2mm x 2mm package with a similar ARM in it, but they can only get 16 pins out at that scale, 4 are power and ground, one is clock leaving you 11 pins to rule the world.

- Tuna-Fish 15y agoThese are not sold as physical chips, but as logic macros, where someone implementing a soc pastes this on with all the other stuff he wants. The total chip size will of course be bigger so that it can have pins.
