Ermm... I just read the SAM4 series ARM micros on the atmel site...looks like good stuff coming up! running at 120MHZ and lot more powerful features!
My question is how is ARM different to UC3A chips? Should I start studying the SAM4 for the future projects instead of UC3A sereis chips? I have been writing codes so far on UC3A chips. But I am tempted by the frequency of operations and the extra RAM! :D
