The writer was on an episode of Embedded.fm podcast awhile back, one of the rare ones where they really get into embedded in detail. Good episode, I recommend it. Two take-aways were that he just loved the Silicon Labs EFM series, which is a modern set of peripherals wrapped around an absolutely outdated 8051. For the most part micros are just moving things from one peripheral to another and that can work out just fine. It's nice SI used SWD/JTAG as the debug peripheral so you can program it along side all the ARM parts you're actually going to use. And two... Having used almost everything on this list. I'm going to chose the ARM M0/M0+ 10 times out of 10 anymore. Maybe I prefer STM's peripherals to Atmel's event-eccentric, or whatever. I just can't honestly see starting a new project today on 8051, PIC16/24, AVR etc. Maybe it's what you're used to. Or maybe for someone making landfill-ready toys with razor thin margins, but I'm glad that's not me.

>8051 TI is still pumping out Zigbee boards based on it. I had to dig through documentation and tick a box saying I wasn't going to make missiles just to figure out what I needed to program it. I'm kinda curious about 8051 chips. They're absolutely everywhere, although maybe now the Espressif chips are taking over.

  8051 is OLD, Espressif is far newer. I like the amount of support that ESP gets but would personally never use it because I told trust Chinese networking chips. The 8051 makes absolutely no sense to anyone - except when you consider the extreme low cost. In the example of the SiLabs parts, they took the modern peripherals from their ARM chips and plopped them down to a 8051 core. Some times that will work great, but if you are doing any “real work” (preocessing) on chip just go with ARM. But, he, sometimes you need to toggle some LEDs and write something out over SPI.
