Microcontroller and microprocessor based integrated circuits that are based on 32-bit processor cores with peripherals and tool support are known as ARM based processors with developers. Commonly known ARM stands for Advanced RISC Machine.
This 32-bit processor is similar to AVR 8-bit product with a difference of architecture used in both. Microcontrollers consists of conventional internal registers, internal program memory and RAM.
Students should start with 8051, then PIC, then AVR, then they can move to ARM. Now a days ARM is widely used in Embedded Systems Field. So knowing ARM will be helpful during job searching also.
Career options open when learning on microcontrollers increases. Some of the available options are: Embedded System Architect, System Software Engineer, Embedded Engineer, Firmware Engineer, File System Engineer, Embedded software engineer.
Due to the low power consumption and high performance industry needs microcontrollers for the purpose of sensing, monitoring and controlling irrespective of the specific need and industrial automation. All industries have the requirement of power optimization and here comes the need of setting up and programming microcontroller.
