Does anyone know if Atmel has a product lifetime road map for their AVR devices? I can't seem to find one on their web site. I just noticed that the ATTiny26 is "not recommended for new designs" and would like to know how long they are expected to be produced for. -- -Mike

Distributors can't order anymore of them. There seems to be plenty of Attiny26-8SU around (200,000), but less of other packages. If your product really needs that chip, you should buy up life-time worth of inventory.> > -- > -Mike

Just need to find something else suitable for the next product. Won't be a problem as they have lots to choose from. :-) -- -Mike

Reason: they keep changing and dropping the product lines at all time. Atmel does not provide for the 100% compatible replacements, which means that the whole lot of work has to be redone, the procedures have to be changed and everything has to be tested again. This is not acceptable for the embedded applications in my field. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com

You might have to go unleaded (SU) sometimes in the future.> Just need to > find something else suitable for the next product.

If your product really > needs that chip, you should buy up life-time worth of inventory. >Not really true. You are confusing "not recommended" with Last Time Buy. "not recommended" means simply that. The company reselling the product, thinks that you are better off by designing in another component. In this case, the ATtiny261 Sometimes this means that it is planned to be obsolete, and sometimes there are other reasons. I know of one part which was in production for 15 years after beeing stamped with "not recommened for new designs". Searching for "Debugwire", in the ATtiny26 datasheet, might give you a hint, why it is better to use the ATtiny261. -- Best Regards, Ulf Samuelsson This is intended to be my personal opinion which may, or may not be shared by my employer Atmel Nordic AB

I'll look it up.Not always. There is also such a thing as a 'go away' price on older parts !! We've just helped someone with a Freescale 'not for new design' device. The original part IS still available (but fading), but price is now over 3x that of the equivalent newer replacement part. (but they do have to move to SMD, which they were doing anyway..) -jg

I think a normal behaviour for semiconductor companies is to mark a part as "not recommended" for new designs, and then inform the sales force about the roadmap for obsolecense. The LTB itself is is a formal process starting with the announcement of LTB, giving certain time for the customer to order parts. This is mostly, but not always followed in my experience. By making sure you get these announcements, you also ensure you will be updated with the roadmap.>> I know of one part which was in production for 15 years after beeing >> stamped with "not recommened for new designs". > > AT-S1200? >Not an Atmel part.>> Searching for "Debugwire", in the ATtiny26 datasheet, might >> give you a hint, why it is better to use the ATtiny261. > > But no doubt more expensive.
