Micro-Controllers  
 
 

Micro-controllers are small computer used for sensing input from the real world and controlling devices based on that input. Most electronic devices you use today have a microcontroller in them of some form or another. Micro-controller are built for the purpose of dealing with specific tasks, such as displaying information in a microwave LED or receiving information from a television’s remote control.


Microcontroller includes a CPU, RAM, ROM, I/O ports, and timers like a standard computer and they are much smaller and simplified so that they can include all the functions required on a single chip. Microcontrollers were originally programmed only in assembly language, but various high-level programming languages are now also in common use to target microcontrollers.

There are several different levels of microcontrollers and microcontroller systems. Some are very small, chip-size devices to which you have to connect your own electronics. Others are larger, composed of several components and ports for input output, ready to plug right into other devices. Microcontrollers are used in automobile industry, control and automation, robotics, home appliances, industrial appliances, electronic gadgets, communication equipment.


Some Features of Micro-Controller are

1.Central processing unit - ranging from small and simple 4-bit processors to complex 32- or     64-bit processors.

2.Volatile memory (RAM) for data storage.

3.ROM, EPROM, EEPROM for program and operating parameter storage.

4.Discrete input and output bits, allowing control or detection of the logic state of an    individual package pin.

5.Serial input/output such as serial ports (UARTs).

6.Other serial communications interfaces like I²C, Serial Peripheral Interface and Controller    Area Network for system interconnect.

7.Peripherals such as timers, event counters, PWM generators, and watchdog.

8.Clock generator - often an oscillator for quartz timing crystal, resonator or RC circuit many   include analog-to-digital converters, some include digital-to-analog converters in-circuit     programming and debugging support.

 

Courses and Eligibility

1. Student must pass higher secondary education or 10+2 with any subjects to get     admission into bachelor’s degree program.

2. BE in Electrical and Electronics.

3. M.tech in Electrical and Electronics.

 

Employment

Graduates in this field are employed in all the industries which are involved in manufacturing computer products.
