What AVR chip sets do you use the most? Is there a specific set that lends itself more the the hobby set or is it just the ones readily available in DIP packages that become popular. Are their better options in SMD packaging?
Thoughts? Ideas? Rants?

Atmega seems to be the most used avr family for hobbyists these days, with the arduino and whatnot..
-
yes but what specific atmegas do you use? I've seen several part numbers and I'm interested in branching into the xmega series (the fixed the I2C hardware bug) but I want to find out what the most common items are so I can figure out what packages are available and pick the one that supports the most people

If you want to get outside the typical Arduino 328/640, the mega644 is a fairly popular device since it has been the largest DIP atmega out there, so it is easy to start prototyping and move to a SMD

Do a google search of each one, then record the number of results. Then graph it for us ::)

With WebbotLib I started with all the usual stuff: ATMega8/168 and the AtMega640 for the Axon(s).
All the other processors I support have been explicitly requested by users (see http://webbot.org.uk/WebbotLibDocs/object.jsp?id=27737 (http://webbot.org.uk/WebbotLibDocs/object.jsp?id=27737) for a list).
DIP through hole stuff like the ATMega644 offers 64kprogram space but at the expense of features like Timers/PWM channels etc offered by their SMD relatives - purely due to lack of pins. eg the ATMega640(SMD) has 5 timers but the ATMega644(DIP) only has 3.

What about the other AVR series are they compatible code wise to most stuff jest better hardware or smaller in some cases? Specifically the xmega and the tiny series. I personally want to mess with the xmega series for the Ill fated and Ill named OSCAR project. They supposedly fixed the I2C hardware bug but as far as stats go I have not had time to dig in to them yet.
