content: Most Rasperry Pi compute modules now have 12 week and more delivery times. Mouser lists some popular ones (like the CM3+/LITE 94AC6633) with delivery in December.That's nearly 7 months.Better start ordering if you need these.

content: Broadcom being fabless does take a toll in this environment. I was reading an ExtremeTech article on how decisions 20 years ago are impacting us now:https://www.extremetech.com/computing/322695-why-we-cant-build-our-way-out-of-the-semiconductor-shortageI remember thinking at one point that most popular uC like AVR, PIC, MSP and STM32 run their own fab lines and have less volatility for hobby boards like Arduino. It assumes other parts are also not affected.

content: Quote from: hindenbugbite on May 14, 2021, 04:02:06 pmYes, the big MCU vendors run their own fabs. I think I recently saw a comment from an MCP executive that Microchip does about 60% of their production in their own fabs.It is worth mentioning that very little MCU production is on a node smaller than 40nm, so the 5/7/10nm capacity that Apple, AMD & nVidia aren't competing with your STM32. I would be interested to know what the "state of the art" process is inside TI or Microchip's own fabs.

content: I've been in electronic manufacturing since 1978 and if this indeed takes 2 years it will be the first one in all that time.Normally there is a bloodbath in 6 months - probably because that is how long it takes for those with money and power to buy up the production pipeline for the quoted lead time which is 6-12 months right now. After that stock is delivered, the whole thing collapses because these customers stop buying until this stock (which they had no use for, since there is no underlying increase in end user demand) gets used up, which takes a couple of years, and then it all starts all over again

content: Quote from: peter-h on May 18, 2021, 01:56:02 pmI would guess there is even a reduction in demand, as a result of the prices sky-rocketing and consumers/ end users/ engineers finding alternative solutions...

content: Only a matter of time until a futures market evolves. Instead of ordering parts from DigiMouse, you'll have to buy calls for October STM32H747XIH6.And God help anybody who gets stuck with actual parts on the shelf. You'll be laughed out of town, like the trader who accidentally ordered a tanker of crude oil to be delivered to the financial district.

content: The price of crude oil went negative last April, due to a shortage of storage capacity at the ports (Covid again). Tankers stayed away to hold the product until storage and prices became rational.Seehttps://www.cnbc.com/2020/06/16/how-negative-oil-prices-revealed-the-dangers-of-futures-trading.htmlandhttps://www.bbc.com/news/business-52350082
