Micro Controllers.

Micro Controllers

Micro controller is a electronic device(IC) and which is small computer built as a one component. In a micro controller, there are many modules built in for cut down external components to be used with it.

General Internal Modules in Micro Controllers.

• Analog to Digital Converter,
• Timers,
• Oscillators
• SPI Bus,
• I2C,
• RS232(serial),
• Parallel  ports,
• USB, PWM(Pulse Width Modulation),
• Interrupts generators,

Features of Micro Controllers

• Very low power consumption is better for battery powered devices.
• Programming and designing is very easy than Micro Processors.
• There are thousands of micro controller models in the market with different capabilities. 
• Low cost.
• Easy to program and design than Micro processors.
• Working without any other external components(not all).
• Re-programmable internal Flash Memory
• Save more space of the circuit board and decrease additional components. 
• Assembly, C, C++,Java supported.
• Project boards for testing and for studying usages.
