MICROCONTROLLER PIC 16F877, Features, PIN diagram, PIN description
Most of the enngineering projects are done with the help of Micro controller. In this series, i would like to share the MICROCONTROLLER PIC 16F877, Features, PIN diagram and PIN description so on.

 High-performance RISC CPU
 All single cycle instructions except for program branches which are 2 cycle
 Operating speed: DC - 20 MHz clock input DC - 200 ns instruction cycle
 Up to 8K x 14 words of Flash Program Memory,
 Up to 256 x 8 bytes of EEPROM data memory
 Pin out compatible to the PIC16C73/74/76/77
 Interrupt capability -up to 14 internal/external
 Eight level deep hardware stack
