There are STM32s in Digikey

Alas, not in our package. But maybe things are breaking.

I've just had 100 32F417s, QFP100, delivered from, guess who, Farnell! So I think better times will come soon, but you can rely on the distis to say as little as possible while they milk the market.

The STM32 theory of economic recovery

We use STM32F207IGT6, LQFP176 package, in several products. The question is whether we should gamble on them becoming available, and design them into a new product.

They are being quoted from possibly dodgy distributors. One distrib takes orders and payments and never delivers. Nice business model.

We's just buy 1000 if we could trust the source.

why the F207? seems to me the F407 is more common, it is probably pin compatible just just faster and with an FPU, M4 vs. M3 core

I don't know. Some people selected it last year, as a replacement for an EOL NXP part for new designs. It seems plenty fast.

The applications are mostly bare-metal, fairly undemanding instrument controllers. An FPGA often does the heavy lifting.

We still ship products with 68332's, still available. It is older than some of my engineers.

maybe it was cheap, I see lots of boards with and people using stm32f4xx don't think I've seen any with stm32f2xx

Or someone got large inventory to push it to John. F207 is CM3, older design. F4xx is CM4.

afaict the F2xx was announced in 2010, the F4xx in 2011, so not much difference

Yes, also other sites are showing stock

Maybe we are soon getting back to normal. Will be interesting to see if prices go back to normal

Pandemic shortages made a lot of manufacturers of various products realize "ugh we've been selling this stuff way too cheap all along" I think

(producer inflation).

And workers are receiving too little for their labours (wage inflation)

or just too much money around (M1,2,3 inflation)

or just (soon to be double digit) inflation.

Right. And why doesn't a box of Kleenex cost $40?

More so in the less fungible commodities like you can use toilet paper as Kleenex in a pinch, but you can't use a Chevy as a BMW

I get the store brand paper towels for a buck right now, I think in 2019 they were 99 cents

I doubt it; this is just the usual cyclic thing, where a shorateg is artifically created (by various events, which usually merge into the distis telling everybody that x is on allocation, upon which the users shit themselves and multi-order everything they can) and then collapses a year or so later.

This will go the same way.

I have quite enjoyed designing out parts by Mr Ripoff (Maxim) and replacing them with ST parts, and some TI parts.
