Impressive price point. I'd like to understand, what can you realistically do with these?

The 48 bytes of sram are enough to encode several state machines. It has pwm and dedicated IR signalling output, but no ADC for input.

It's generally designed to be a very simple controller-of-things. Push an up button, increase the pwm output up to some limit, etc. remote controls, fans, etc.,

Indeed. I've seen a retail toy use a similar microcontroller from Nyquest to accept infrared control commands and drive some H-bridge drivers to make a simple, cheap RC car.

Use a neural network to detect numbers? (Well, this runs on a slightly more capable MCU, though)

Most simple home appliances - microwave, air fryer, mixer/blender of some sort.

Toys, like a house which blinks lights and plays tinny music when a button is pressed (as long as speech / complex sounds atr bot involved)

Remote control toys (with external transceiver)

Make a LED candle?

It looks like this chip is powerful enough to run a more "cinematic" looking gust/wind/topple/rise flicker model: https://blackdice.github.io/Candle/

The 38kHz signal support clearly indicates that this is a TV Remote Control chip.

Yeah, you can find them in all kinds of low-cost remote controls:

Nothing.
