A few years ago, I inherited dozens of tubes of 8051 MCUs, specifically the Atmel AT89C51ED2-IM. I know they're old - and clearly tons of much better MCUs exist - but they'd be useful. (Plus, it just feels wrong discarding 100+ good chips.)
Any suggestions what Keil (or other) product to use, which programming gizmo, and possibly a dev board? I'd like to spend as little as possible as this is hobby stuff. 8051 assembler or C is fine.
So far, I've found these but am uncertain if they'll work:
I understand that Arduino's can be used for the programmer / loader, but apparently the "C" type Atmel's I have need a more sophisticated programming device than the "S" types (or is that incorrect?)
Any assistance is greatly appreciated. thanks!
I mentioned the eBay angle since there is such a huge supply chain issue right now and someone might be in desperate need. Having said that, the old parts like this are not affected as much, but they will still be rare probably.
From that one Errata it looks like the keyword is FLIP. I would research that angle:
