Could somebody with a good understanding of microchip production economics explain what the price difference would be if all 8-bit chips (such as the Atmega328) were replaced by otherwise equivalent 32-bit or 64-bit chops tomorrow (that is, same production capacity and unit counts sold)?
How much would it cost, in cents, to just have those extra bits?
- omeid2 2y agoSupply-chains are more complicated than merely the unit price. Things like existing stock, talent, software, product design, certifications (both chip and products based on chip), and hundreds of other things play just as substantial role.
- LeFantome 2y agoProbably more about ecosystem compatibility at this point. There are already RISC-V chips that sell for less than a 6502.
- anthk 2y agoI doudbt about that stance, you can have 6502's on every keybard at ridiculous prices.
- Palomides 2y agoa cheap 32 bit RISC-V chip like the CH32V003 goes for about $0.10, and the cheapest MCU I've heard of (PMS150C, barely useful for anything) goes for around $0.03 there's little real point in 8 bit chips anymore
- fulafel 2y agoEven without special knowledgeon production economics, I dare say there would be a race to produce replacement compatible 8-bit microcontrollers to get people's stuff working again.
