Well, these original maverick analog competitors are together now:

Maybe I'll combine their databooks on one shelf!

Analog devices is eating everyone. All our parts will start from A in the future.

Not

Clustered around some universities are fab-less design houses; professors and students have ideas that they want form for.

Advantage to large as they'll have preferred access to wafer fabs (usually not an issue except for now)

I find the shortage issue rather strange.

 

I have often thought that Semiconductor companies have "too big" an inventory.

Surely a Fab can do a large production run of X identical Wafers quicker than X different Wafers.

Likewise it must be easier to package the chips in one particular package type.

 

So popular items like TQFP ATmega328PB would go to the front of the queue.   And a DIP packaged ATmega88 might have a long(er) wait.

The new chips could be prioritised.

 

Yes,  there would still be unhappy customers.    But Microchip would keep most people happy for most of the time.

The big commercial customers must be more important than hobbyists.

 

Does Microchip really need so many package and temperature options ?

I feel sorry for Molex...just for one connector type

want 2 pins, 3 pins, 4 pins....30 pins 

tin, brass, or bronze contacts

standard, gold plated, or selective gold , this thick, that thick

regular plastic, or fire -rated

white, black, yellow, green, etc

right angle or straight?

locking tab?  no tab?  friction fit?

PC mounting barbs?

Any combo of the above!!!

Yes though will trim their catalog due to manufacturing issues that are unresolvable.

Military and Industrial packages perhaps.I didn’t notices where the NXP chips around (the one that I contact employee in my countriy here)🙏🙏🙏

The models of some Maxim Integrated parts entered LTspice immediately after the beginning of this year.

The consolidation of the last ten years has been amazing.

I reckon the following consolidated companies own this market (embedded and general electronics) now:

 

Analog Devices

Microchip

NXP

STMicroelectronics

Texas

 

With Nexperia, Vishay, Onsemi supplying the rest of the discrete semis.

 

Between them they do pretty much everything we would ever need: power supply chips and modules, sensors, microprocessors and microcontrollers, logic chips, analogue chips and convertors, transceivers and comms chips, etc.

 

The only thing I don't see above is programmable logic (Xilinx and Altera) which is more for the high end electronics people (comms and military).

 

Shame you can't buy many of their products...

Semiconductors are long lead time; realized by the ones at Toyota (11Mar'11), realized by the rest of the world a decade later.

Funnily enough I was going to add Diodes Inc (Zetex) but didn’t want to pad the list. I know them well as they are or were based in Oldham, England and I used to work with some of their staff when I was an FAE.

 

And I did think about Lattice but more because of their low power CPLDs and FPGAs than for the high end FPGAs that Altera and Xilinx make. Very useful for assorted logic but so many of the micros nowadays have everything built in - sram interfaces, dram interfaces, XiP and QSPI, assorted serial interfaces, some even have serdes so prog logic becomes much less needed.

 

I did consider Renesas, who do good Cortex processors and software libraries for them, but they don’t have the market share that STM, Microchip etc have. Ironically when I was an FAE the Atmel DataFlash memories were one of my specialities, then those flash product lines were spun out as Adesto, which was then bought by Dialog, and is now owned by Renesas. And my employer has a subsidiary which uses gazillions of the DataFlash chips.

 

Which all kinda goes to prove my point that so much technology has been subsumed into so few companies that you don’t need many others (except as you say for JFETS, FPGAs, and other rare stuff). Even Skyworks (I was their UK FAE when it was Alpha semiconductor) and Quorvo (I was their UK FAE when they were Triquint) are now both conglomerates and not just RF companies.

 

I am daily amazed by the history I have seen in my electronics career alone. And the stories from before then scare me - Bob Widlar etc.

 

As for supply, o’ Lordy where do I begin? 79 week leadtimes for some parts and in big volumes (not quite Amstrad volumes before Cliff chimes in, but still some pretty big industrial numbers) and you get no favours in this market. I am surprised no big companies have folded - it must be killing cash flow.

Okay I’m a pedant too, but TI has been nicknamed Texas for so many years that the denizens of said state have to take second place…

Funnily enough I had a meeting with an FAE the other day in a local cafe/restaurant (my office still isn’t allowing visitors in due to covid restrictions, so just meet the sales rep/FAEs in cafes).

 

He is the Ireland FAE for products from Analog Devices, Hittite, Linear Tech, Maxim and Dallas. Poor fella must be helluva confused...

 

I hate to think what all products the Microchip FAEs must cover.

Opposite from what I can recall though dated (April'16 acquisition of Atmel by Microchip Technology)

Investors attracted by backlog?

Another round of acquisitions?

Renesas Electronics Corporation (Fitch Ratings, 15Jan'21)

... and the largest microcontroller supplier with 19% market share, according to research firm Gartner. 

...

Market share pie charts are likely in recent electronics journals.

The problem with one persons own view is that you are fundamentally a single sample point. I don’t see Renesas much compared to STM, Microchip, etc but I am acutely aware that is my single observation. 19% is a good number considering the hundreds of companies who make Arm cortex micros. I sometimes call this thinking the Microchip effect after all the die hards who refuse to move from Microchip Pics even thought there are better micros. I can only see what I see… therefor that is all there is.

 

When is say big companies folding I mean the customers and OEMs not the chip companies - they are raking it in, but the customers must have horrendous cash flow problems, especially the subcontract manufacturers who are waiting for one silicon chip to arrive so they can build all while having had to pay for the other 99% of the parts ages ago.
