8051 Microcontroller Schematic Diagram. The pin diagram of 8051 microcontroller consists of 40 pins as shown below. The following image shows the 8051 microcontroller pin diagram with respect to a 40 pin dual in line package dip.
Now lets explain and go through each in detail. In 1981 intel introduced an 8 bit microcontroller called the 8051 it was referred as system on a chip because it had 128 bytes of ram 4k byte of on chip rom two timers one serial port and 4 ports 8 bit wide all on a single chip. A microcontroller can also be referred as a microcomputer.
It has an 8 bit processing unit and 8 bit accumulator units.
The data bus is utilized to carry data from specific operations. For an 8051 microcontroller clocked read more. Where each port contains 8 pins. A vcc power supply and ground is also shown.
