content: Hello, friends!There's someone here who lives in Milan, isn't there? Is STM really building a factory near this city? Can anyone confirm that?

content: In the Russian profile news on electronics I heard that STM is building a plant near Milan. I have a new development aimed at all the main components of STM. I really want to have information about the reliability of this manufacturer and prospects. Now I need a decision to stay on STM or go to another manufacturer.

content: Quote from: daqq on February 02, 2021, 09:08:51 amLook at this "reliable manufacturer" on the site for the presence of STM32F103Vx.They are gone, only small remnants in the sellers warehouses are shown. The Chinese comrades told me "everything is fine, we have it", but the price increased by 2 times.

content: Quote from: vad on February 02, 2021, 09:53:15 amIn Russia, there has long been a production of Cortex MCUs, I am just studying the possibility of using them. But they are designed to work with a direct hit of an atomic bomb and are very expensive.But you needn't be ironic, there are other MPU manufacturers, such as TI, Microchip, GigaDevice.

content: Quote from: S. Petrukhin on February 02, 2021, 10:00:30 amYup, market shortages happen occasionally for every single source part - there was this great Atmel AVR scarcity a few years back if I remember correctly, a few others I can't name of the top of my head. And the MLCC shortage. And so forth...

content: QuoteWhich doesn't help anything if exactly those "modern, better, cheaper alternatives" also have lead times of about 50 weeks or so, as nearly all STM Cortex devices seem to have at the moment. I think that is it, what S. Petrukhin is worried about.Edit: quotation formatting fixed

content: As far as I know it's a foundries supply issue going on, has nothing to do with STm being a reputable supplier.For you're needs I'd guess they're as good as any other major vendor, and you could be facing similar issues with others throughout this year.Well maybe some suppliers using foundries in mainland China could have a more stable supply this year, especially with you not facing any restrictions from them... but just guessing...

content: Quote from: S. Petrukhin on February 02, 2021, 10:26:14 amYes, I also heard about those. They are the largest Cortex MCUs in the world, and come in a package with 14 pins and two carry handles for portability.PS. Not sure about Milan, but STM had (and from what I see still has) fab plant in Singapore. I lived within 10 minutes driving distance from it. Not sure if this information helps in your selection of Cortex-M vendor.

content: I did hear recently that NXP is will be pulling out of MEMS production and transfer everything to STm, not sure about exact detail, but the fab should be in EU from what I remember. Could be the one in Milano.My company is going back and forth between NXP and STm for mems accelerometer, for various reasons - supply, quality, qualification (automotive)... and I've been involved in some of the qualification procedures from the SW PoV, and about 3 months ago our MEMS expert mentioned this about STm fab in EU taking over completely MEMS production...I would expect their cortex production do be done at one of the big foundries in TW, and not at their smaller fabs in Europe.

content: Quote from: vad on February 03, 2021, 02:51:15 amYou can't just buy in an online store. Probably, some contractual arrangements are needed.I haven't contacted the manufacturer yet. Still, this is a slightly different MPU, not a complete analog of the STM32, different peripherals.GD32 is a simpler replacement.

content: Quote from: S. Petrukhin on February 02, 2021, 10:00:30 amAnd had STM given any guarantees on long-term availability of that part which they subsequently forgot about? I guess not. STM is obviously a reputable and reliable manufacturer, but that does not mean that they will never discontinue a part...If long-term availability is important to you, base your design on parts with guaranteed long-term availability. All major manufacturer have these series, often designated "for automotive use". STM guarantees 10 or 15 years of availability for these, from the date of market introduction.
