I started looking at the NXP LPC2368 series, but these have not been available for a while. Now I am looking at the Atmel AT91SAM7X256. It is in a 100-pin LQFP package, which is going to be easy to mount. I want to avoid BGAs. The NXP chips started at about $7, the Atmel is a little more expensive, around $10. Either one is still a GREAT deal for what you get! The NXP chip is supposed to run at 72 MHz, but there were problems when it ran that fast. I think the Atmel is a little slower, but still probably a lot faster than an 8-bit CPU at even 100 MHz.
