Pin Diagram And Description Of 8051 Microcontroller Electronics Desk The 8051 microcontroller is a popular 8 bit microcontroller widely used in embedded systems. it is a single chip microcontroller with a harvard architecture that includes a cpu, ram, rom, and several peripherals. the 8051 microcontroller has a 40 pin dual in line package (dip) that provides various inputs and outputs for communication with. Pin 20 (gnd): pin 20 is the ground pin of the 8051 microcontroller. it represents 0v and is connected to the negative terminal (0v) of the power supply. pins 21 – 28 (port 2): these are the port 2 pins of the 8051 microcontroller. port 2 is also a bidirectional port i.e. all the port 2 pins act as input or output.
Microcontroller 8051 Pinout Diagram And Pin Description Etechnog 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. Intel corporation is the first company who presented 8051 microcontroller in the market. it is an 8 bit microcontroller. it has on chip 128 bytes of ram, 4k bytes rom, two timers, one serial port, and four general purpose input output ports. each port has an 8 bit register. In the above discussion, the block diagram of the 8051 microcontroller is presented, along with a brief description of all components and elements to understand the architecture in a better way. moreover, the pin diagram of this controller is also part of the discussion above. it shows how different pins are divided into different categories. 1. pins from 1 8. port 1: the pins in this port are bi directional and can be used for input and output. the pins are individually controlled; some are used for input while others are used for output purposes. 2. pin 9. this pin is also called ‘reset pin’. this is used for resetting the microcontroller to its initial values.
