How come STM32s are not available? I thought the chip supply issues were mostly related to smaller process nodes while these should be made on relatively older

No there's an everything shortage in electronics. Fancy chips, old chips, power chips, capacitors, connectors, epoxy resin. https://www.digikey.com/en/resources/reports/lead-time-trends https://www.digikey.com/en/resources/reports/lead-time-trend...

The short answer is that they are not building more fabs for non-leading edge processes, like those used by STM32. There is an interesting video about this: https://www.youtube.com/watch?v=YJrOuBkYCMQ https://www.youtube.com/watch?v=YJrOuBkYCMQ

  There are variants of STM32 that are 90nm. A 90nm foundry was just announced. Not sure if they’re planning on making STM32s, probably not, but there are non-leading edge foundries being run and more are being made. Here is an announcement from this month https://www.eetimes.com/skywater-to-build-1-8-billion-fab-in-indiana/ https://www.eetimes.com/skywater-to-build-1-8-billion-fab-in...

  Pretty interesting, thanks!
