Normally, this isn’t huge news. The 8051 is the most copied microcontroller on the planet, and there are probably billions produced each year. Cheap parts are only cheap if your time is free ...

The T8051XC3 core implements one of the smallest-available 8-bit MCS®51-compatible microcontrollers. The core integrates an 8051 CPU with a serial communication controller, flexible timer/counter, ...

There are dozens of different ARM cores alone, hundreds of 8051 clones ... be the best microcontroller for that application. Or whatever you have sitting around in the parts drawer, we were ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.
