PIC16F877A Microcontroller

PIC stands for Peripheral Interface Controllers (PIC). PIC microcontroller is a family of Harvard architecture microcontrollers made by Microchip Technology. PIC microcontroller which know as a single-chip microcomputer, well suited for control and automation of machine and process in electronics and have more attractive features that suitable for wide range applications. PIC is popular due to their wide range ability, availability of low cost or free development tools and serial programming capability.
             
            PIC16F877A is a small integrated circuit (IC) available with 40 pins package. This PIC is a powerful and very easy-to-program CMOS FLASH-based 8-bit microcontroller packs introduced by Microchip Technology.

             The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2 – wire interated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
