1.5 c Microcontroller alert.
Very low-end, but 38kHz support is explicitly called out in its product manual. This means that this tiny uC is ideal for TV remote control (or other IR-blasters).
I wouldn’t recommend anyone use this chip unless you were some kind of professional saving pennies. Typical $1 uCs are far easier to work with and have exponentially more power (even $1 8-bit uCs). Still, its an interesting thought experiment for what a 1.5 cent uC could be used to implement…
What did you use to program it?
Oh nothing. I’m just theoretically interested in this part.
In practice, I’m not moving off of the AVR tool chain or chips. AVR does more, and I’m spending like $20 on PCBs in practice anyway so 1.5c chips and $1 AVR chips both basically cost the same to me.
Heck, $20 in various chips isn’t very expensive for a project in practice.
AVR is good. Though, I have the XGecu and Microchip IDE (The windows 98 looking one). It does a good job with PIC MCs. Surprised there isn’t a command compiler for Microchip ASM like CC. Someone would surely have made a linter and autocomplete for NVim as well. Anyway…
Older chips are made obsolete because of higher power consumption paired with worse performance. I am surprised it is viable to make them at all, let alone at 1,5 cents per. Obviously a lot of manufacturers clinging to old familiar roads.
Not long ago having own PCB design meant bank breaking, organ selling investment.
I really appreciate that I have proof that I am not able to make anything useful to humanity, and money is not the cause. To mineself I can be true now… 😞
