Come on guys, don’t exaggerate.
Ten years ago, I was convinced that the 8051 was immortal. And now? Sure, you can still get it (from Atmel for instance), if the original used the classic 44-pin footprint. But for how long from now? Anyway, it’ll cost much more than, say, a Cortex M0+ processor. And if you need one of the gazillion formerly existing pinouts (like the LPC9xx series from NXP), you’re out of luck.
