Well, sort of. It depends on your BOM cost targets. I remember seeing (a few years ago now) an AVR in a tiny 6 pin surface mount package about 0805-ish size. 8 bit micros are the new 555.
I have a friend that does a lot of consumer electronics development on contract. One of his favorite parts is an 8 bit micro that cost 6 cents in bare die, and that was a few years ago. The part is probably 4 cents now. A 4 dollar ARM looks rediculous next to a 4 cent part in certain application spaces.
But in my world - low volume mechatronics - the ARM with 1mb flash is the no-brainer choice.
- petra 9y agoAny idea where could one get that 4 cent mcu and how to assemble it ?
- pryelluw 9y agoThose are volume prices.
- dbcurtis 9y agoChinese supplier. It comes as passivated bare die. You glue it to the board, need a wire bonding machine to attach connectivity, and thn encapsulate it with a blob of epoxy. Serious volume stuff. The dev kit is a few hundred bucks though, so it is reasonable to work with. Reply if you are still interested. But if you aren't already assembling in China, it probably isn't for you.
- SpacemanSpiff 9y agoHey, any chance your hardware developer friend could spare a few minutes to talk about his/her work? I'm a freelance hardware+software developer and there's not many of us out there it seems. It would be great to get some feedback on some long-term business goals. You can reach me at contact5m4t@peakdata.io Thanks!
- coupdejarnac 9y agoI'm one too, and I lurk on several subreddits these days.
- jpm_sd 9y agoOT, but are you from Jarnac? A good friend of mine lives in Tilloux
