You said there is a 230 part? I'd grab that and change the footprint, at least most of the pins will have the right names.

You can definitely use the FT230X to communicate with & reprogram an ATMega; as others have said there's no DTR on the chip but AVRDude pulses RTS so just tie it the same way and all works well.

I ordered a MicroFTX (http://jim.sh/ftx/) to evaluate the chip and it's been working reliably on various breadboarded designs for a few weeks now.

Regarding the availability -- early versions of the X chips have a USB bug that's supposedly been resolved with the new Rev D chips that are just coming out. I actually got an email from Mouser on Friday that the chips I ordered in October should be shipping the 16th; I just checked DigiKey and they say they'll have them on the 13th.

Well said...good idea.

Can find them in stock :(
They only ship in January 2013 at Mouser.

I guess I'll stick with the 232 for now.

Sorry about that! At least it will work.ß

I just received notification from Mouser that they've finally got the FT230X in stock. They only have the QFN version; the SSOP package still shows no availability until Jan 7.
