Hello all!

I've been playing a little bit with an Arduino One and I'm a little curious about this: does anyone know what is the size of the transistors in the ATmega328p? I was looking for some answers in the web, and the only reference I found was a blog ( http://rajeshkovvuri.wordpress.com/2011/11/01/atmega328p-and-atmega328-what-is-the-difference/ ) talking about the differences between 328 and 328p and guessing the process of each one. Does anyone have more information?


Thaaaanks in advance :)

"does anyone know what is the size of the transistors in the ATmega328p?"
Very small.

"Does anyone have more information?"
Probably not. You could browse at atmel
http://www.atmel.com/products/microcontrollers/avr/megaAVR.aspx
and see what you can find.  I don't recall seeing anything in the '328 datasheet.

Yeah, that's the thing... I've also read the datasheet and the info isn't there :( I guess it is some secret architecture design stuff, so I was hoping someone knew something, but I was quite convinced already that there wasn't going to be any official information. Thanks anyway! ^^

In the ATMEL forums they've just answered me this:

"Early AVRs were on 0.35um, later they used 0.18um then since they closed the Atmel fabs and outsourced I think they're now using 0.12um"


So, I guess that Atmega328p is 0.18um...
