Basics of PIC16F877a: Ports & Applications

Hello guys, today I will show you the basic Introduction to PIC16F877a. PIC16F877a is a PIC Microcontroller and is normally used in Embedded Projects like Home Automation System, Bank Security System etc.

PIC Basic Properties:

• It has 40 Pins.
• IT has 5 Ports in total. ( PortA, PortB, PortC, PortD and PortE).
• It supports Serial Communication for which it has 2 Pins TX and RX.
• You can receive data from RX and can transmit data from TX.
• It also supports SPI Protocol.
• We have to place a crystal oscillator ranging from 4MHz to 40MHz.
• We have to design its basic circuit first in order to use it.
• Moreover, we will also need some programmer or burner to upload hex file.
• I use PICKit3 in my projects.
• Here's an image of PIC16F877a:

Ports in PIC16F877a:

• PortA has 8 Pins in total and it is an analogue Port.
• All Pins in PortA are analogue.
• PortB also has 8 Pins but these all are digital Pins.
• PortC is also a digital Port having 8 Pins.
• PortC Pins are also used for Serial Communication.
• PortD has 8 Pins and all are digital Pins.
• PortE has 3 Pins.

PIC16F877a Applications:

• It is normally used in Embedded Systems Projects.
• It is used in robotics.
• It is also used in automation projects.
