Prerequisite – Difference between Micro-controller (µC) and Microprocessor (µP)

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 MSP430 comes under the family of micro-controller. MSP430 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. MSP430 micro-controller :
It is a 16 bit family of micro-controller from Texas Instruments, first introduced on 14 February 1992. It is one of the simplest micro-controller and it is designed for low cost and, specifically, low power consumption embedded applications. It is a mixed signal micro-controller means a single IC has both Analog and Digital circuits. MSP430 micro-controller is based on Von Neumann Architecture. It can be programmed using various IDEs. It is relatively faster than PIC, AVR and other micro-controller.
