I wonder if the war has anything to do with this actually. These chips and some larger STM32 like F7 and H7 are dual use and can be used in missiles and drones. I couldn't buy the car manufacturers' excuse. I think MICs around the world have been stockpiling these chips.

I was working for a customer (medical) last 12 months with a Zynq design. I remember at the time the distributor specifically saying they were being instructed to give priority to US companies on their stock as it arrived (I assume defense).

They had to have a meeting with higher uppers at the distributor to scramble about 200 pieces industrial grade from them (that was basically a year's worth of production for that product, low volume production).

So I have no doubt that whatever mil contractors need they will get it.

Situation is dire even for contractors unless your product is already in production and has somebody on the government side advocating for you.

I know the Cyclone V specifically is used in the MiSTer project (https://www.retrorgb.com/mister.html), I'm not sure how big a part of overall demand that is though.

I don't think STM32 MCUs are that special, not are they related to Intel FPGAs. There are plenty of STM32 clones out there and manufacturers have moved on.

[varispeed]

Clones of more advanced STM32 don't exist. There is GD32F4xx but it's not as powerful as the originals and I doubt anyone in the right mind would use these where reliability is paramount.

Raspberry Pis too. The shortage feels targeted. Or I’m just being an idiot as always.

This is the official statement of the Raspberry Pi Foundation on this topic:

> https://www.raspberrypi.com/news/production-and-supply-chain...

Excerpt:

"As we’ve said before, the current situation is as much a demand shock as a supply shock: demand for Raspberry Pi products increased sharply from the start of 2021 onwards, and supply constraints have prevented us from flexing up to meet this demand, with the result that we now have significant order backlogs for almost all products. In turn, our many resellers have their own backlogs, which they fulfil when they receive stock from us.

These backlogs absorb Raspberry Pi units as fast as (or faster than!) we can produce them, with the result that little of our production volume ends up being immediately available on reseller websites. Where units do appear, bots often attempt to scalp stock which is then resold at higher prices elsewhere."

Different perspectives are given in the answer https://raspberrypi.stackexchange.com/questions/139020/why-i...

In particular, the following alternative explanations are discussed (which don't exclude each other):

- industrial customers are given priority

- there are currently deep changes in the Raspberry Pi Foundation happening

The fact that they are shipping new PCB revisions of their boards with alternative components (like different PMICs) supports the claim that (at least) part of the shortage was due to supply problems.

Pine64 has some pretty nice ARM (and fairly priced) boards that seem to be in stock. Maybe one of those will suffice for your application?
