We are working on designs already <2 years where the part was new when we designed it in, and was moved to end-of-life already. Would not surprise me if Freescale was acquired in the reasonable future...

On the other hand, my complaint with Atmel is that they are not moving fast enough with AVR. They are wasting too much resources with AVR32 and ARM. We have been waiting years for a part to fill a gap between too big too expensive and too small cheap enough. The announcements came months ago, but no sample available and minimum order of 1K and months of delivery. How do they expect us to design with AVR? We are currently looking for alternatives. > > Would not surprise me if Freescale was acquired in the reasonable > future... I wish someone (other than microchip) would buy the AVR line from Atmel.

Or, how long the *core* for that part is available (i.e., in various "flavors")? [many of your examples are hardly "newer uControllers"] > I have googlet a lot, but not found anything useable.

Well, _I_ would like a detailed report about the profitibility of all the companies that I might like to invest in that is 100% accurate and extends out to the next 10 years. Then I won't have to work. Any and every microprocessor in the world today will be available forever, or until the manufacturer loses interest (check out Intel's history on this), whichever comes first. Since that doesn't help at all, the best you can do is check how manufacturers have done historically on this point (i.e. Microchip = good, Intel = bad bad bad, Freescale = usta be good, probably is good, but who knows with all the changes, etc.). -- www.wescottdesign.com

It can also vary significantly within a manufacturer's product line. Many vendors have specific parts that are planned to have much longer lifetimes than others. Of course plans change... The short answer is start asking the distributors and reps that have been trustworthy in the past. It's their job to help you with stuff like that. -- Grant |
