I can't believe I'm saying it in a uC context, but those ARM chips looks too small. :) All of the I/O can be replaced by external chips over SPI or I2C *except* the GPIO. You never know when someone will design a motherboard that will need *this* pin bit banged as fast as possible. If that's not a real GPIO on the uC, everything goes south. So, I do like those chips, but they don't fit this use well. Wow, those are some small ARMs. Any idea what they're going to sell for? It looks like they're a little premature right now. Cheers, David
