Pin Diagram And Description Of 8051 Microcontroller Electronics Desk The pin diagram of the 8051 microcontroller is used for various purposes in embedded systems. some of the main uses of the pin diagram are: interfacing with external devices: the 8051 microcontroller has several input output pins that can be used for interfacing with external devices such as sensors, actuators, displays, and communication modules. The pin description or pin configuration of the 8051 microcontroller will describe the functions of each pins of the 8051 microcontroller. let us now see the pin description. pins 1 – 8 (port 1): pins 1 to 8 are the port 1 pins of 8051. port 1 pins consists of 8 – bit bidirectional input output port with internal pull – up resistors.

8051 Microcontroller Pin Diagram And Its Working Procedure Lekule The pin diagram of 8051 microcontroller looks as follows −. pins 1 to 8 − these pins are known as port 1. this port doesn’t serve any other functions. it is internally pulled up, bi directional i o port. pin 9 − it is a reset pin, which is used to reset the microcontroller to its initial values. pins 10 to 17 − these pins are known as. 8051 microcontroller pinout diagram. it comes in different 40 pin packages such as dip (dual inline package), qfp (quad flat package) and llc(a leadless chip carrier). pin configuration diagram of 8051 is shown below: some manufacturers also introduced 20 pins 8051 with less number of input output pins. Therefore, the microcontroller 8051’s pin diagram and explanation is given below. port1 (pin1 to pin8): port1 includes pin1.0 to pin1.7 and these pins can be configured as input or output pins. pin 9 (rst): reset pin is used to reset 8051 microcontroller by giving a positive pulse to this pin. port3 (pin 10 to 17): the port3 pins are similar. The general schematic diagram of 8051 microcontroller is shown above. we can see 3 system inputs, 3 control signals and 4 ports (for external interfacing). a vcc power supply and ground is also shown. now lets explain and go through each in detail. system inputs are necessary to make the micro controller functional.

Pin description of 8051 microcontroller. vcc – pin number 40 – 8051 operates on 5 v of the supply voltage. thus this pin is solely assigned to v cc at which the supply voltage is provided. gnd – pin number 20 – this pin is allotted to ground, that passes the excess current of the microcontroller to the ground.
