I am supporting an ATmega128 product that would benefit from the extra RAM in an ATmega1281. But these are not yet available from catalogue distributors in the UK, and the usual franchises are showing long lead times (and disproportionately high purchase costs).

Is anybody buying these parts in volume and, if so, do they work correctly?

Regards,

Colin

Maybe try out a 2561, which seem to have hit the distribution channels nicely. DigiKey shows ~US$10/qty. 100. A Mega128 is about $1 less.

You can put lipstick on a pig, but it is still a pig.

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

On the ATmega2560/2561 check for compiler support and if you currently use the original JTAGICE you will need the newer JTAGICE MKII. These 256k FLASH chips have a 17 bit program counter with 2 new instructions and 3 byte long address push/pops. Not all compliers have managed to support this yet.

The ATmega640 and ATmega1281 appear to be the last ones left that have not made it into distribution channels yet.
