[sdiy] Contemplating DIP microcontrollers

[Michael Zacherl.]

Hi,

a while ago I started to look at the Atmel XMEGA MCUs 
(ATxmega384A1 ATxmega256A1 ATxmega192A1 ATxmega128A1 ATxmega64A1)
which seem quite promising to me.

The eval board looks nice:

I also found a note that there's an Arduino port in the works:
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265563522/0
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1269500888

The ADC/DACs are just 12-bit and the micro is not DSPpowered like the DSPics but the entire package and the Arduino environent looks quite tempting to me.

Michael.  :-)
