STM32 Roadmap?

(1/16) > >>

I have been designing solutions around STM32 for over 15 years, right from the F103 days. The most complex projects have been with F4, simpler applications with F1, F0, Lx, Gx, etc..
As a result of the ongoing Chipageddon situation, most silicon manufacturers have lost my faith. Since my clients and I have put a huge investment into the STM32 family, I am really concerned about how ST is going to proceed with that family. A quick online search for "STM32 roadmap" didn't bring any enlightenment. The "10 year guarantee" is of not much use, when it comes to a F407. At this point and being a simple freelance engineer, I don't expect a useful answer from ST, should I address them directly.


Question: is there any information out there, regarding which way ST is going to develop the STM32 family? What devices should one use for the next redesign?
At the moment the F407 from the "High Performance"-range would be my biggest concern, simple because of the code complexity. At the same time I am also interested in "Mainstream"-range items. During Chipageddon we already did several redesigns to keep things going with the devices that we could procure. E.g. replacing F407 with smaller FLASH versions, or replacing F1 with any small, slow and buggy A-revision Gx's that we could scratch from the bottom of the barrel.

I am aware of STM32 clones and other ARM MCU's. Let's stick to genuine ST in this thread, please.

I expect them answering to this question on tomorrow's event.


So the deadline is past, and although I don't have time to sit through a 1.5-hour video, I did take a look at the STM32 product page and tried a google news search for "stm32" and I don't see much in the way of new MCU development.  (The new MPUs are interesting to some, I guess.)

Still no Cortex M55 or M85 parts with the Helium SIMD.  Nothing with neural coprocess (Ethos).  Nothing exciting on the process front either (anyone remember FDSOI?).  No foray into RISC-V either.  I would need at least one of those to pique my interest.

Everyone knows there is a long lag time between ARM's announcement of new cores and real silicon, but if
you compare with Cortex M7, this has already been a longer wait than normal---the M55 was unveiled more than three years ago, and there are still not even vaporware new-product announcements from ST.

That being said, they promised an update on the supply situation... Did anyone tune in to hear what they had to say?  Just being able to buy parts from their current product line would be fantastic in the near term.  But IMO a lack of new products in the pipeline bodes ill for the future.

Looking at chips I have used over past 30 years, I reckon the 32F407/417 will be in production for another 15-20 years.

ST is in a similar ballpark to Hitachi (now Renesas). Once they get loads of design-ins they tend to keep making the parts. H8/3xx had a 25 year production run and I'd say the 32F4 has had more design-ins. Even in the heyday of sales engineers, Hitachi offered almost no help at all. Painfully, one could extract information on stuff not in the data books.

And then ST will chop some package options, narrowing it down to some tiny BGA package.

These 168MHz-180MHz chips deliver 10x the power of previous generations, which is nice, and necessary for stuff like USB and ETH. The later ones might do 500MHz internally but they risk getting too far ahead of market demand. The applications that need that are far fewer, and you have to charge more for the chips to maintain product spectrum differentiation; this is a key marketing requirement even if it is completely bogus in terms of production costs.

And at the same time you don't want to drop prices on the older chips because nowadays that is a real no-no. The name of the game is shafting everybody who is not big enough to not get shafted. That in turn limits how much you can charge for the later chips.

IMHO the most important thing is to avoid brands which drop parts faster than a whore's knickers - like Atmel ;)

In Russia, everything is very simple - there are simply no ST products.
We use everything that can be used, even very strange and scary solutions. The main purchase opportunity.
