Where are release dates of MCUs are stored

[ASche.5]

Would need release dates for:

L433 - guessing from searching around 2017

L152 - guess 2015

L552 - guess 2018

L072 - guess 2016

has anybody a way to find out or the data?

Thanks a lot

Wikipedia? Press-release (PR) type stuff, although this might occur before general availability..

Release/revision date histories of relevant documentation?

L5 appeared in 2019

The individual models may have appeared later, e.g. 'L4 family was introduced with the mid-range 'L476, and 'L433 might've appeared one-two years later.

You can also look at the respective datasheets' revisions dates, although the very first revisions may have been not public.

The entire data to this topic makes it confusing and I was hoping to find something official from ST.

press releases and way back machine did not get me to pin point this. Wikipedia points to little bit different dates then the picture that you linked @Community member​ .

Thank you for your insides and ideas! @Community member​ thanks for writing down the classic forensic methods it confirms my fears that it might be the standard way to find out and it explains the different dates found out there. ChatGPT by the way came up with same unsure answer ...

In the end I was trying to make a alternative estimation for life time of the MCUs - for this I asked as IHS database is estimating nearly same life time for all of them. But L152 is just NRND. And is obviously older then L552. I am a little bit new to deal with sourcing issues of designs for very long life products. It seems hard to

thanks and if you have any ideas about the life time estimation part please let me know.

ST is more interested in communicating the future dates than dwelling on the past.

If you looked, the info would likely correlate more with trade shows dates than EOL dates.

I think the approach is wrong.

They are going to kill products based on popularity and sales numbers, yield issues and an ability to make them. Some of the things that were flagging up were coming from fabs that wanted to build other things, and the ability to move production and create new mask sets, testing, packaging and the entire cost/benefit analysis there.

Samsung moved one IC fab I was using to LEDs for consumer lighting. Other fabs have burned down, whilst others have lost critical test equipment that was beyond the manufacturers service/commitment drop-dead dates.

ST needs to be killing things off faster, and funnelling customers into other parts, or at the very least a much smaller subset of SKUs.

The portfollio and the support of it has become unmanageably large at this point.

From discussion with support I found that the dates at right of : https://www.st.com/content/st_com/en/about/quality-and-reliability/product-longevity.html#10-year-longevity&section=FM141-10-year

are the start date for the 10years and that those are updated. Further as soon as something goes NRND it means no hope for upgrading to this year + 10 years.

Now event the rough release dates can be used to make estimation of sorts...

@Community member​ : Sourcing is B.. these days - to many parts on the marked and two much growth pressure annoying but its the world we living ...
