HI!
thank you all for sharing your knowledge and time, as a contribution I can say: you do not need the external 32K oscillator , my Arduino DUE have not incorporated and works perfectly (this is for use with the RTC that I think it is better to use an external one for the possibility of a battery backup as DS1307).

did you compiled a sketch in ARDUINO IDE 1.5x and you load in a ATSAM3X8CA?
I wanted to do that in the beginning, but due to lack of information and components (in my country do not get these chips) finally I didn't , but it was in my plans, I wish you could confirm this.
greetings
Erick
I compiled it on arduino 1.5.8.
When I plug usb connector to windows machine I get following in my device manager:
In arduino IDE I can see board as:
The BOM is here:
