I've been happily working with AVR's for some time now. Recently, I've decided that I should at least evaluate if the AVR32 UC3B's are a better choice for some of my applications.
So... I've been trying to do my homework -- looking over the literature and spending quality time reading the data sheet. Either I'm blind, ignorant, or both(*), but I find the UC3Bxxxx data sheet sorely lacking.
To be specific: The UC3B0's have three USART's, and the UC3B1's have two, according to the data sheet. OK, I'm cool with that. But I've been on an Easter egg hunt trying to find which one is left out of the B1's. The B0's do USB-OTG, the B1's only do device mode -- but the necessary I/O still seems to be brought to I/O pins. Same for USART's, the I/O seems to be brought through the mux... and that's just the stuff I *know* I don't understand.
Anyway, I am missing some big piece of this puzzle, or am overlooking something, or haven't found the right document yet.... or.... it's a secret only divulged over lunch with an FAE.
Anyway... please, somebody, whack me with a clue-stick. Where should I be looking?
