uC lifetime
in [Embedded]

From: JeGy on 13 Dec 2009 05:11 Hi, I need some kind of analysis/report that covers lifetime, production time, market availability, etc. for newer uControllers, e.g. PIC, AVR, ARM, H8, etc. I have googlet a lot, but not found anything useable. Anyone knows about such a report? Thanks in advance, regards Jens

I doubt if you'll find much available online - information like this might well only be available at a price, or under an NDA. Manufacturers dislike having to commit themselves to guaranteed lifetimes, but they also dislike telling people that they will /not/ guarantee a lifetime for a product - therefore they prefer to remain mostly silent on such topics. The exception is for devices targeting a market where long lifetimes are essential (such as automotive or military markets), in which case it is worth their while to make promises.

Microchip has historically scored very well in this regard, despite the huge number of different parts.

I assume this means that they still have the old fab equipment to make some of those ancient parts like the SPO256A-AL2 and CTS256...

I Motorola/Freescale is good with old parts availabitity, too. Intel and Atmel are the opposite: they drop product lines just like it. > assume this means that they still have the old fab equipment to make > some of those ancient parts like the SPO256A-AL2 and CTS256... I guess Freescale redesigns old parts for new technologies. How could you explain that modern HC12 de-facto can run at ~70MHz, while old datasheet specifies 25 MHz? VLV |
