It's a clone of an intel chip from the 80s. It's still used to make new stuff. Here's a video of it

- Sanddancer 10y agoThe 8051 family also has a huge amount of support tooling for it -- compilers, validation tooling, etc. For a lot of jobs where the 8051 lives, a new architecture would just mean an expensive set of validation tests for no real benefit.
- HeyLaughingBoy 10y agoYup. The serial relay boards I resell are controlled by an 8051 variant. Those things are everywhere
- hydrogen18 10y agoWow, you're right. I figured an 8051 was popular, but its derivatives make up >50% of the embedded market it seems. I am guessing most clones offer more than 128 bytes of memory.
