Microcontroller was designed by Intel in 1981. It is an 8- bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of four parallel 8- bit ports, which are programmable as well as addressable as per the requirement.

Today, 8051s are still available as discrete parts, but they are mostly used as silicon intellectual property cores.

Arduino boards are present in logic 5 volts and 3.3 volts. This makes arduino more versatile than 8051.
