STM32L1 NRND'd

[waclawek.jan]

One of my friends noticed, that ST NRND'd not only the STM8, but also the whole STM32L1xx family.

However, in contrast to STM8, the 'L1 are under the 10-year commitment program, so they should continue to be available in the next 9 years.

Hello Jan,

The STM8 MCUs had also the 10-years commitment program.

The commitment seems predominantly to supply, rather than support.

The development and engineering support seems to have already been defunded or redeployed.

I missed this nuance, as from my garage-scale perspective I never expected support beyond the public, which won't go away.

Btw. I wonder, why is it a mere user who announces this sort of things in ST's forum?

It probably also means that (as far as ST are concerned) you can do better with an alternative part also from ST.

Better? It might mean lower current, cheaper, peripherals with fewer bugs.

But unless/until availability improves it’s all a bit academic.

First of all: availability is already improving, depending on the family, better stock levels will soon be seen.

Then on the subject of STM32L1: yes, the family has been put on NRND, but is still on the Product Longevity List. However, there is still plenty of time until 2032 to switch to another pin4pin compatible family.

And yes, there will be a pin4pin compatible family as a replacement at the right time, of course again with 10 years of commitment - stay tuned, you can be curious.

And finally, on the subject of STM8: yes, these devices are no longer on the product longevity list for the next 10 years - you can work out the rest.

However, the STM8 were still used for various reasons, of which the 5V compatibility should not have become quite so important by now, but their interesting price should have played a major role. And this is exactly where the recently launched new STM32C0 family comes in, aimed precisely at replacing many of the previous STM8 (not STM8A, this is a complete different story). Advantages of the STM32C0 should be quickly apparent: the same development environment as the (perhaps already used) STM32, similar pinout as STM8, considerably more computing power relative to the price, etc. Yes, there are exceptions, such as the STM8S208 with CAN, but this can easily be replaced with the STM32F042 (which is available again) or its bigger brothers.

I realise there will be a lot of discussion on the topic STM8, but really this thread is about STM32L1, right?

Yes, I'd like to see people migrate from 8-bit, but everyone complains about why this adoption doesn't move faster, or occur.

One of them is that things that could be a physical drop-in replacement, with a little thought and effort, seem to be ignored. There's a lot of reasons why old designs aren't migrated, not least that the engineers, or source development materials aren't available.

More healthy places do periodic design review and refresh cycles to establish if long lived products can be cost reduced or optimized.

Others wait for the factory to burn down to make a decision to change..

As Clive said above, the competition will quickly come and eat this piece of the pie.

PS Okay, and so the STM8 were *never* part of the 10-year commitment, or you've just simply erased them from that list?

Hi @Peter BENSCH​ ,

> And finally, on the subject of STM8: yes, these devices are no longer on the product longevity list for the next 10 years

So, the STM8 were never part of the 10-year commitment, or you've just simply erased them from that list?

@Community member​ Um, it may be that I got the STM8 mixed up with the STM8A. But anyway - STM32C0 is meant as a possible alternative for STM8, which are definitely on NRND.

News.

As spotted by Philipp Klaus Krause, one of the principial developers of SDCC, STM8 were un-NRND'd.

So, I looked at the 'L1, too - the newer ones from them (as witnessed by the -A suffix on some of them) appear to be un-NRND'd too:

and although only the older ones appear to be still NRND'd according to the product list:

 

the 10-year commitment list lists all of 'L1 as NRND with the end-date not renewed and to be expired at Jan 2032:

 

Btw. the STM8 (except automotive) are in the 10-year commitment list listed as Active but with non-renewed expiration at Jan 2032 too:
