PIC16F676 Microcontroller Overview

PIC16F676 is a microcontroller good for learning and experimenting for engineers because it has high flash memory rewrite cycle. The controller has 2KBytes flash memory which is enough for starters to develop basic programs. Also the 12 GPIO are designed for handling 20mA current (LED driving capability) by which beginners can connect peripheral at hand with less caution.

PIC16F676 has very few features and it cannot be used for developing advanced applications. It is used for developing small applications (like display driver) and for developing programs by beginners who want to enter microcontroller platform.


How to use PIC16F676 Microcontroller

Any microcontroller is needed to be programmed before installing in any system or application. So first we need to program the controller PIC16F676.

Entire process of programming PIC16F676 goes like this:

  • First list all the functions to be executed by this controller.
  •  Next write these functions in ‘IDE software’ using ‘C’ language.
  • This IDE software can be downloaded for free on company website.
  • After writing the desired program compile it for error elimination.
  • For a successful compilation IDE application generates HEX file for the written program.
  • Choose the programming device (usually ‘PIC kit 3’ or ‘PIC kit 2’) which establishes communication between PC and PIC16F676.
  • Connect the programming device to microcontroller appropriately.
  • Run the HEX file dumping software which is related to the chosen programming device.
  • Choose the appropriate program HEX file and burn this HEX file in PIC16F676 flash memory.
  • Disconnect the programmer and connect the appropriate peripherals for the controller.

After connecting the power, the controller executes this HEX code saved in the memory (which is written program) and creates response as instructed.



  • Beginner applications
  • Hobbyist projects
  • Display units
  • Development board for learners
  • Embedded systems like scrolling displays and meters
