nice little FPGA

That's a kick ass part if I ever see one :-)

Then TI has an OTP CPLD for 22 cents.

And dirt cheap, will probably buy a bucketful before they are all sold...

This is definitely a killer... It can probably do something very complex and blindingly fast that can't be done with an expensive 50 cents (in singles) PIC or Chinese 24MHz Cortex M0+ with 3K RAM and 20K Flash in TSSOP-20 with UARTs, Timers, I2C, UID, SPI and other stuff in it, programmable in GCC without any special IDEs, working from 1.7 to 5.5 Vcc... Way to go, demand will be probably enormous...

Dang, someone bought em all, only 2 in stock

A lot cheaper than a 22V10!

AMD's chip at the topmost link intrigues me most. Its data sheet:

"Some Versal adaptive SoCs have an array of signal processing cores that are highly optimized for functions in machine learning, convolutional neural networks, wireless radio, backhaul, cable, and radar applications. The array consists of a number of AI Engines, each comprising a 32-bit scalar RISC processor, fixed and floating point vector units, data memory, and interconnect. AI Engines can be used as a single tile, as the complete array, or at any granularity in between. The creation of custom acceleration and compute engines in the AI Engine array is done at a high-level through C and C++."

I suppose TI made an enormous blunder in designing their PLDs and creating the code-free dev tools. Those Texans are all notoriously dumb.

We're blowing up big attenuators too. We have about a square inch of pulse generator circuit making 8KW 10ns pulses that are hard to measure. I guess we'll have to design our own attenuators. We were thinking we could make them like business cards and give them away at trade shows.

Keep typing! [1]

I am always impressed that anyone would sell a transistor in a SOT23 package for 1 cent or a 1% resistor for half that. Why bother?

Tastes better. I'm finishing a cup of Peets French Roast this instant; time for my refill and some bread pudding.

The only things that you never get tired of are addictive.

Be sure to get a spare, in case (the first) one breaks.

When clients send us stuff, we always ask for “one to use and two to blow up.“

Mo was making oatmeal (for herself, not a horse) so I had toasted flatbread with honey. She said my breakfast looked like something out of Oliver Twist.

"Please sir, no more!"

Nobody has said so, but we're pretty sure they are.

And we wish europe would stop having wars that we wind up paying for.

It should be easy to replace with my old Radio Shack soldering iron.

Damn, looks like I'm late to the party...

imagine turning on a new board for the first time with something like this on it,

Pretty high in onesies—maybe it’s cheaper in reels?

The main application of interest is presented in the data sheet, power supply sequencing. Getting the main processor to sequence its own power from cold and dark would be a neat trick but...EDN over the years is full of "design ideas" i.e. "garbage hacks" for supply switching/power management that being able to roll your own into a custom IC starts to seem pretty nice. Glue logic eats up board area but off the shelf power management ICs all seem to be overpriced and never do exactly what you want, anyway.

I don't think that device has them but if you spend a few more pennies you can usually find CPLDs with PMOS open drain outputs which are nice to have for power sequencing applications, uPs usually don't have open drain PMOS pins.

Yeah everything is obsolete except for the 50 cent Cortexs according to people who only do software for products shipping 100,000+ units or do projects according to their own timeframes.

But designs that meet requirements, have guaranteed supply availability and get prototyped/turned around the quickest are often what a client judges the winner and those solutions do end up in products moving hundreds of thousands, because in my experience when a problem is amenable to being solved by a CPLD or mixed-signal array, the solution often comes together amazingly quickly.

Like, days or even hours, we're in the "agile electronics" era. Clickty click click click, there's your custom power-sequencer chip, there's the simulation output verifying performance, spin the first board revision, nobody got time for GCC..

The only war in Europe at the moment is Russia's invasion of the Ukraine. Trump doesn't to spend US money on weapons going to the Ukraine to fight off the Russians, so Europe has taken over paying for them.

Trump's attitude is pretty much Chamberlain's at Munich - except that Chamberlain knew that the UK needed a year or so get their armed forces up to war-fighting strength, and Trump's attitude is pretty much dominated by his lust for photo-opportunities, ideally including being award the Nobel Peace Prize. Since his lunatic tariff antics have now been declared illegal he'll probably have to settle for the publicity associated with him being successfully impeached.

I think that 'blower upper' was almost a designated role. Sort of a 'trial by ignorance'.

The Safety/Standards/ISO docs guy in the suit was my favourite choice, after I'd determined that everything was bullet proof. Alternatively, the department head, or even the owner of the company.
