PIC16F877A 8-bit PIC Microcontroller

PIC16F877A is the most commonly used entry-level 8-bit PIC Microcontroller. It is a 40-pin 8-bit Microcontroller with 14kB of program memory. It does not have an internal oscillator but can work up to 20MHz with external oscillators. The controller has 8 ADC channels with 10-bit resolution and also supports PWM on 2 pins. It has two 8-bit timers and one 16-bit timer and supports communication protocols like UART, SPI, and IIC. You can also check other PIC microcontroller Components.

Programming PIC Microcontroller

To program the PIC microcontroller you will need an IDE (Integrated Development Environment, a compiler, and an IPE (Integrated Programming Environment).

IDE: MPLABX v3.35

IPE: MPLAB IPE v3.35

Compiler: XC8

Microchip has given all these three software for free. They can be downloaded directly from their official page.
