A micro-controller is a single Integrated Circuit (IC) which is comparable to a little stand alone computer and it is designed to perform the specific tasks of embedded systems. A micro-controller contains processing unit and small amount of memory (ROM, RAM etc.), few I/O ports for peripherals, timer etc. AVR and PIC comes under the family of micro-controller. PIC micro-controller and AVR micro-controller differs from each other in terms of different architecture and different sets of instruction, speed, cast, Memory, Power Consumption, Bus Width etc. Now let’s understand in detail how they differs from each other.
1. AVR micro-controller :
AVR micro-controller is manufactured by Atmel corporation in the year 1996. It is based on RISC Instruction set Architecture (ISA) and also called as Advanced Virtual RISC. AT90S8515 was the initial micro-controller belongs to AVR family. AVR micro-controller is most popular category of controller and it is cheap. It is used in many robotic applications.
2. PIC micro-controller :
PIC stands for Peripheral Interface Controller. PIC micro-controller was developed by Microchip. This micro-controller is a very fast simple micro-controller in implementation and performance point of view. This micro-controller is easy to program and also it easy to interface with other peripherals.
Difference between AVR and PIC :
|01.||AVR stands for Advanced Virtual RISC micro-controller.||PIC stands for Peripheral Interface Controller micro-controller.|
