8051 microcontroller pin diagram is a topic that is quite usually asked in interviews. Therefore, it is essential for all candidates to have in-depth knowledge about this topic.
The fundamentals related to this topic should be clear to all the aspirants. The first thing would be to research all its concepts and sub concepts that are mostly asked in the interview. This will help you dive deep into this topic.
Know about the pins
The description of pins should be known to all the aspirants as its related questions can be asked from the aspirants. The common description of all pins include:
Pin 1 to 8: These pins are assigned to port 1 to perform the input output operations.Pin 9: This is called the reset or highly active input pin with two machine cycles Pin 10 to 17: All pins from 10 to 17 are assigned to port 3. These pins are quite similar to port 1. They can also be used as the universal input and output pins. Pin 18 and 19: All these pins are connected together with the external oscillator with the motive to provide external clock frequency Pin 20: It is connected with the ground which offers the 0V power supply Pin 21 to 28: These pins are referred to as the port 2 pins which has external memory connected with interfaces Pin 29: The program stored enable or PSEN is an output active pin that helps in reading the external memory Pin 30: It is the active input pin that makes the distinction between the memory chips and multiple chips Pin 31: EA or external access input pin will help enable or disable the external memory Pin 32 to 39: These pins belong to port 0. They are called input/ output bidirectional pins Pin 40: It provide power circuit to supply voltageKnow about the usage of pin diagram
Every learner should know about the applications or usage of pin diagrams. It is basically used as the interface with all external devices. It is also used in providing adequate access for debugging and testing.
Moreover, the pin diagram is known to provide flexibility to customise the functions of a microcontroller.
