Alas, not in our package. But maybe things are breaking. -- If a man will begin with certainties, he shall end with doubts, but if he will be content to begin with doubts he shall end in certainties. Francis Bacon
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
I could use a 100 pin LQFP, but when it is impossible to know what
part is available next week, I cannot.

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. -- Father Brown's figure remained quite dark and still; but in that instant he had lost his head.

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. -- If a man will begin with certainties, he shall end with doubts, but if he will be content to begin with doubts he shall end in certainties. Francis Bacon

maybe it was cheap, I see lots of boards with and people using stm32f4xx=20 don't think I've seen any with stm32f2xx =20
