At $0.20 in 1k quantities, this is TI's answer to the CH32V003, Puya PY32, and the STM32C0 series. It's great to see tier-1 silicon vendors participating in the race to the bottom for jellybean microcontrollers.
The 1KB of SRAM is admittedly very tight (even WCH's 10-cent RISC-V parts usually give you 2KB), so you are strictly in bare-metal, carefully-managing-your-stack territory.

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.

Unfortunately by the time I was ready to order the boards I found the tiny package was unobtanium and had to resort to the second smallest package which isn't very small. Frustration!
Not worth changing the design now...

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.

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.

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?

Can it run Prince of Persia?

It's a bit low on RAM, otherwise it's similar to a game boy advance. Maybe after the GBA, GBA SP, and GBA micro, it's time for a GBA.. nano?

Could you put a few thousand of these on a PCB and have a super duper tiny compute cluster?
