8051 Microcontroller

8051 Microcontroller : ( Reference - 8051 User Manual )

8051 microcontroller is 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, two 16-bit timers and 1 UART. It consists of are four parallel 8-bit ports, which are programmable. An on-chip crystal oscillator is integrated in the microcontroller.
