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

#12I can understand how the material cost is low for such a tiny chip -- it said 337,000 of them fit on a wafer, but testing time must cost more than 1.5 cents per die.
They probably don't test. Yield is likely high enough that failures are the responsibility of the customer. Honestly, this is where I'd love RISC-V to be making inroads. It would be really nice to have a super simple processor with a standard architecture and tooling.
The first link in the article is to a .10 RISCV part. https://zeptobars.com/en/read/Nyquest-Technology-NY8A051H-80...
The RPI2040 is under a buck in bulk (the chip).
The Pine Ox64, The Milk-V duo and the RPI packages are all interesting products (at a sub 10 bucks each).
The MILK-V duo S is very appealing (form factor wise). If they ever mange to get POE/HDMI in version out it will be a killer product (even more so if they get all that into a sub 20 buck price point).

#15What 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!

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.,

> It would be really nice to have a super simple processor with a standard architecture and tooling. Pragmatically speaking, that architecture already exists -- it's the 8051. (This part is a PIC clone, but 8051 is also extremely common.) RISC-V has promise for larger microcontrollers, but really tiny ones like these (48 bytes RAM, 1KB ROM) are better off with an 8-bit architecture.
Ya...8051s are literally everywhere, and there's a vast ecosystem of code and programmer talent to draw on.

No, they _are_ tested during manufacturing. > Honestly, this is where I'd love RISC-V to be making inroads A 32-bit CPU is way too big for this price point still.
With small chips like this do you think they would test at a high sampling level?
