This line of micros has been out for almost 2 years now but they only just took the 1.38mm^2 package out of pre-production. I started a design last year of a tiny earring with ~102 addressable LEDs on it, a microphone, a bunch of supporting circuitry and this micro. https://i.ibb.co/JWh57LLw/IMG-20260408-183807502-HDR.jpg Unfortunately by the time I was ready to order the boards I found the tiny package was unobtaniu…
It seems awesome, but I'm having a problem with figuring out how can a "normal" person use it. How would YOU use it, reader of this comment?
I made and tested it but didn’t care enough to continue.
Earlier quoted context omitted.
Maybe not practical as a cluster configuration, but it could certainly be used as a voice-generating device for a synthesizer, or as a controlling device for MIDI I/O, or .. both even of course, configurable according to the users needs/patch idea.
Yeah, but even for those applications you suffer from limited RAM a lot; with 16bit samples at 48kHz the thing has 10ms of audio buffer (stereo: 5ms) if you don't need RAM for anything else :S The ADC is really nice though, 1.5 MSPS is really good for such a small/low powered thing (fills the whole RAM in under half a millisecond).
A silly question (from a non-HW guy). Why are digital bathroom scales so coarse? Some have a weight resolution of +/- 500 grams. Would a better microcontroller make a weight faster or more presise? I guess this TI micro controller is overkill for a bathroom scale.

These earrings look awesome btw!
Does anyone know what would the price of this be, roughly of course, given that a customer ordered some thousands or tens of thousands? I have no grasp of even the magnitude of the price for something like this.
1-99 $0.720
100-249 $0.48925
0-999 $0.378
1,000+ $0.251

This is why highly accurate scales usually have very low max weights.
Could you put a few thousand of these on a PCB and have a super duper tiny compute cluster?

I'm reminded of TIS-100, a game where you program a cluster of tiny, parallel CPUs using a custom assembly language. It's painful to get basic stuff done, but you can do some amazing things with some effort.
