I'm not sure what you'd do with that, but I think as power consumption drops to 0 on these sorts of thing it might make some remote sensing applications cheaper/easier to deploy, if you could just deploy it with a battery and forget about it for a year or two.
What would be a comparable early computer with the same computational power? Amazing to think how a machine the size of a room is now only a penny!
In comparison to the usual suspects like Apollo guidance computer or TI-83, it has a higher clock speed but shorter word length and extremely limited ram and memory. Precisely due to the cost engineering - this is meant to run simple, limited size programs.

At these sizes, the packaging is probably a significant fraction of the cost. They may also offer a bare die version at Despite its name, this is not an 8051. Looks like this competes with the PIC10F200 which costs dozens of times more yet has a similar "RISC" (that's what they call it, but it's more like an 8-bit accumulator architecture) ISA and general layout.
It seems to use 1ma when on, so if you hooked this up to one of the larger smartphone batteries at 5000 mah, this could run for 200 days.

I didn’t read the datasheet but I imagine it has to have a lower power mode than that. Much larger MCUs can manage an average power consumption far lower and power off the same battery for periods measured in years, not days.
This is simple enough you’d think you’d be able to power it off an EM field directly!

Isn’t that rather a lot of current for what it is? I didn’t read the datasheet but I imagine it has to have a lower power mode than that.

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.,
