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. 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.
Pin Diagram Of 8051 Microcontroller Geeksforgeeks 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. At89c51 pins – ultimate guide to the 8051’s pin configuration. the at89c51 is atmel’s version of the 8051. the original 8051 series (also known as mcs 51) designed by intel was discontinued in 1996. more than 20 major companies still produce their variants of the 8051 or other uc using 8051’s ip cores. atmel’s version of the 8051 is. 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. It is active high pin. it is used to reset. if we apply active high signal to this pin, 8051 microcontroller will reset and turn off all its functions. it will erase all values of registers and it will make all program counter values to zero. figure below shows the power on reset circuitry.

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. 8051 microcontroller pin diagram. 8051 microcontrollers have four 8 bit i o ports p0, p1, p2 and p3. each uses 8 pins: all the ports upon reset are configured as input. when the first 0 is written to a port, it becomes an output port. to reconfigure it again as an input, a 1 must be sent to that port.
