Microcontrollersy A microcontroller (sometimes

abbreviated µC, uC or MCU) is a small computer on a

singleintegrated circuit containing a processor core,memory, and programmable input/outputperipherals.

y A key impact Technology for 21st century 

y Used for special purpose control applications

uP and uC..y One of the main differences is that microcontrollers are usually 

designed to perform a small set of specific functions, for example as inthe case of a Digital Signal Processor which performs a small set of signal processing functions, whereas microprocessors tend to be

designed to perform a wider set of general purpose functions.

For example, microcontrollers are widely used in modern cars wherethey will each perform a dedicated task, i.e. a microcontroller toregulate the brakes on all four wheels, or a microcontroller to regulatethe car air conditioning, or a microcontroller responsible for the cruisecontrol. These microcontrollers will perform few other tasks (if any)

other than those specified. Compare this on the other hand to amicroprocessor in a PC which performs a wide range of tasks related tothe general requirements of a PC, i.e. performing the necessary calculations for a very wide set of software applications, peforming I/O for the main sub-systems, peripheral control etc.

y Microprocessor = cpuMicrocontroller = cpu + peripherals + memory 

Peripherals = ports + clock + timers + uarts + adcconverters +lcd drivers + dac + other stuff Memory = eeprom + sram + eprom + flash

 A microcontroller has a combination of all this stuff. A microprocessor is just a CPU .

Embedded Systemsy An embedded system is a computer system designed

to perform one or a few dedicated functions[1][2] often

 with real-time computing constraints.y Dedicated Computers for Smart Applications

y Embedded systems are controlled by one or more mainprocessing cores that are typically either microcontrollers or digital signal processors (DSP).

y Respond ,monitor ,control external environments usingactuators and sensors.
