Today’s IC Friday entry is the 8bit AVR micro from Atmega. This chip was sent in by a reader, all the way from Iceland.

Hi Nick,
interesting to see the scale of an AVR…
also I’m surprised they do obfuscation on the last metal layer on such a well-documented design.
But my question for today is: did you describe your process of etching the package, and the setup of taking the weekly shots anywhere?
If not – are you willing to?
I’d be interested in chemicals you use, the microscope and the DIY@home-factor of the whole story.

Hi Matthias,
I don’t think that it is obfuscation, I think it is a mesh for shielding purposes only.
In regards to the uncapping process, I will document the procedure next week as I uncap those chips and make a post about it, probably on Thursday. Cheers.
It’s actually an 8535, believe you have a typo there.
