So anyone know what has happened to these parts - XMega256A3. They are not available anywhere. Element-14 (formerly Farnell) has promised delivery by early March. Doesn't really help with our project this month.

I see small stocks of the A3B (whatever that is) at various distributors in several packages. Including Farnell.

'256 for a new design? It takes me 6 months to fill 32KB of program flash; by my metric, then, it is 2+ person-years to get over the '128 size. I suppose you could have graphics fonts or the like.

I've never met a pig I didn't like, as long as you have some salt and pepper.

The 256a3B is almost a completely different chip. PORTE6 and PORTE7 do not exit on the 256A3B, and I think Atmel should really change the distributor inventory link for the 256A3 to not point to the 256A3B. Also, probably not a good idea to use exactly the same suffix for two different parts - we just had 20 boards made with the 256A3B instead of the 256A3 and of course the switch connected to PORTE6 did not work.

With memory, it depends what you use it for. We have 10 logos for a 128x128 screen with each pixel being 8 bits. These logos take around 25% of the 256K, then we have 5 different fonts, and the larger fonts (48pt) take up 10- 20k each. Sure, if you are just using memory for code, 32kB or 64kB is heaps.

OK, let's make it easier. We will take any of the following:
ATXMEGA64A3-AU
ATXMEGA128A3-AU
ATXMEGA192A3-AU
ATXMEGA256A3-AU

Have some salespeople looking. Customer says it is the end of the world if he doesnt get his product (based on ATXMEGA256A3) by the end of February!

Not sure what quantity you're after, but I have 2 256A3's in my drawer here in Sydney.

Let us know which suburb or postcode you are in - I will pass this info onto the customer. We were really after another 10 pieces now. Thanks.

Avnet has the leadtime for the AtXMega256A3 as 127 weeks. It looks like one of the big guys is using the 256A3 and bought up all stock.

We went through the exersise of trying to get these through RS.. They happily accepted the order, gave ETA's, amended ETA's, re-confirmed ETA's, but when they didn't arrive, chased it up and RS UK could not release them for shipment to Australia due to export restrictions !!?. We ended up getting some from Braemac, who had some in stock 128A3's.. Also have 10 or so spare here if you are in a bind.

Yeah, that kind of headache with supply in Australia was one of the motivators to just skip to the cortex-m3s...
