This port doesnt serve any other functions.

Diagram of 8051. It has an 8 bit processing unit and 8 bit accumulator units. The pin orientation of an 8051 microcontroller may change with the package but the pin configuration is same. Pin 9 it is a reset pin which is used to reset the microcontroller to its initial values. In 8051 pin diagram you can see that it has 4 ports p0 p1 p2 and p3 and each port has 8 pin.

The below 8051 pin diagram also describe the remaining 8 pins. Let us have a look at each part or block of this architecture of microcontroller. 8051 microcontroller pin diagram. Consequently it consists of 8 pins starting from pin 32 to pin 39.

We have already discussed the architecture. Following diagram is 8051 microcontroller architecture. The pin diagram of 8051 microcontroller looks as follows pins 1 to 8 these pins are known as port 1. Pin diagram of 8051 microcontroller the 8051 microcontroller is a 40 pin plastic dual inline package pdip.

However in 8051 there exist multiple pins which are assigned more than one signal. A complete computer system manufactured on a single chip is called a microcontroller. The below image describes the pin diagram of 8051 with respect to 40 pins. Pins 10 to 17 these pins are known as.

Microprocessors microcontrollers by roshni y leave a comment. 8051 is an 8 bit microcontroller that contains 40 pins of dual in line packaging. The functions of the pins of this microcontroller are as follows. Ports of 8051 microcontroller port 0 the port 0 or p0 is a general purpose io port.

The 8051 microcontroller has two buses and two memory spaces of 64k x 8 size for program and data units. However this port can also be utilized as a multiplexed address and data bus from ad0 to ad7. What is a microcontroller. Out of the 40 pins 32 pins are allotted to io ports.

Along with these common features a. The 8051 microcontroller block diagram components along with their functions are explained. As mentioned in the previous tutorial 8051 microcontroller is available in a variety of packages like 40 pin dip or 44 lead plcc and tqfp.
