SAM3X8E PCB design example

Sun Nov 03, 2013 1:20 pm

We're a group of students at master level planning to build an instrument for satellite attitude determination using the AT91SAM3X8E microcontroller. Right now I'm in the electronics group and right now I'm doing as much research as possible to prepare for the PCB design.

According to page 1411 of the data sheet http://www.atmel.com/Images/doc11057.pdf:
SAM3 Oscillators are low power oscillators requiring particular attention when designing PCB
systems. A board design example is given on Atmel’s website in the MCU Technical Center
Section.
That sounds brilliant I thought, but my enthusiasm decreased when I was not able to find said design example. Am I just useless at searching, or is the data sheet obsolete?

Not exactly sure what the data sheet is referring to,,, however, if you are looking for a reference design you can view the design and manufacturing files (including gerbers) for the sam3x-EK.

Find them here http://www.atmel.com/Images/SAM3X-EK__KitsFiles.zip

These are located on the ATSAM3X8E page http://www.atmel.com/devices/SAM3X8E.aspx?tab=documents

Thank you!

I actually found those files after I had started this topic. When reading the data sheet I did imagine something even more educational so to speak, but I guess this will do fine :)

Hi rottemark,
i'm a beginner with sam3x8e so can you share the schematic for meand help me to answer that can i write the code with the atmel studio 6 and program by the native usb.

Hi.

The schematics that I was looking for have been linked to by jharley in the first reply.

Unfortunately I had nothing to do with the coding part, so I cannot help you with that.
