Hello.

 

I have a Xplained XMEGA A1 board which contain the faulty ATxmega128A1, however I also got new ATmega128A1U ICs(100pin TQFP) which is what is on that Xplained board.

 

I am hesitant to do what I plan to do and as such wanted to ask you about it, what I wonder is:

Why would/could I not replace the faulty XMEGA on the Xplained with the new A1U chip?

 

As long as I am careful with the removal there shouldn't be any difference as far as pin layout is concerned right?

 

Regards

Comparing the pinouts, it appears they are compatible.  IIRC, PORTD6 and PORTD7 are N.C. on the A1 Xplained, so there won't be any circuitry hanging on the A1U's USB.

A1U is LVTTL and LVCMOS whereas A1 was almost.

DAC is different.

BOD levels for the better.

Otherwise should be pin hardware compatible.

A new board costs ~$30 - is it worth it ... ?
