I am currently in the process of deciding what attiny I am going to use as "default" for various projects (I'd like to stick to one type as much as possible).
In the race are currently attiny85 (8 pin), attiny84 (14 pin) and attiny861 (20 pin). After studying the datasheets of all of these, I have come to the conclusion that they're all the same, apart from the number of actual i/o pins and a few details.
Actually the only functional difference I could find is that the 861 has a bit more sophisticated timer and it has a second "external" interrupt pin.
Is this correct, or did I miss some important detail?
