Hi all,

I was searching the ST website for a statement about the longevity policy of the STM32 controllers but I couldn't find anything. I thought there was something like that from some congress talk given by an ST FAE.

Any information about it is greatly welcome

Thanks

I can't say I've seen anything, though I've found ST more reliable in not spinning/shrinking the die all the time, with all the engineering issues that causes. I know MICRON has been making some long promises, but basically at a Form/Function level.

The most common driver for silicon being dropped is lack of customer purchases which kills things a lot quicker than promises, and mergers/consolidation of suppliers. Another bigger killer is the deprecation of third party packaging solutions, pick the QFP over BGA.

In the former regard the STM32 is a very bigger seller.

Officially?  Difficult to see the future is.

The F1 series was introduced in 2007 and they are still available.

F2 2010

F3 2012

F4 2011

Some of the older ST7 parts are starting to go NRND and these are 10+ years old.

so I guess 10 years.

I would think your product will go obsolete long before end of life of the CPU.
