Is it really allowed? Can I use an external oscillator that outputs 32MHz into the XTAL1 pin? The datasheet doesn't leave it clear what's the allowed frequency range, and I was under the impression that other than the 32MHz internal RC osc, 32MHz was only achievable via the PLL or the other xLL's.

It is clearly stated in the data sheet.

*blush*

 

So, we can indeed do it. That's good. Thanks for the info.

By the way, I'm still not finding anything like that on the ATXMEGA256D3 datasheet nor the manual. I looked all over the System Clock and Clock options section and did several searches for many keywords, but still not finding it. I'd assume 32MHz external clock is indeed allowed on the XMEGA256D3, but where do I find it?

Open the PDF, press Ctrl + f, enter "External Clock Characteristics" and you should find it.

Maybe you are seeing "XMEGA D MANUAL"?
It's not a data sheet, it's literally manual.

 

 

This is the data sheet.

I did search on both the manual and the datasheet. But the one I have looks different from those images you posted. Maybe its an older version.

But anyways, thanks for the info. I'll indeed use a 32MHz external oscillator. Probably this guy: https://www.digikey.com/product-...

 

And thanks to you as well I just saw (on those images you posted) that there is an ATXMEGA384D3, which (looks to me that) is just an ATXMEGA256D3 with more memory! That'll be big for my project! I'm taking that I can just replace my 256D3 with this 384D3 and only make minor adjustments on my firmware; no PCB changes. But I'll look a bit deeper on the datasheet/manual before. I do remember checking a couple of months ago and the ATXMEGA256D3 was indeed the one with the most memory. Is this one new? Hmmm...

 

And again, thanks man.
