Close-up shot of the 87C752, an 8051 with EPROM. The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168.

[Steve’s] got it working by porting the 8051 assembler over for the Arduino, but we’d recommend adding a level converter to his hardware setup to step down from the Arduino’s 5v logic to the ...

The MilkV Duo is a new microcontroller that combines dual RISC-V processors, allowing one core to run Arduino or RTOS and the other Linux. ... along with an 8051 MCU core.

Californian start-up MicroCore Labs has announced an 8051 soft processor core, four of which will fit into 1227 LUTs on a Xilinx Artix-7 FPGA. The core is called MCL51. “Because it is based on a ...
