Is Called By Microcontroller?

A controller is used to control a process or aspects of the environment. One example of the application of the microcontroller is to monitor our homes. As the temperature rises the controller to open the window and vice versa.At the time, the controller is built from logic components as a whole, thus making it bulky and heavy. Afterwards.mikrokprosesor used so that the overall controller into the PCB which is quite small. Until now, we still see the controller which is controlled by a microprocessor usual (Zilog Z80, Intel 8088, Motorola 6809, etc.).



The process of ongoing downsizing of components, all the components needed to build a controller can be packaged in a single chip. Thus was born the single-chip computer (one chip microcomputer) or also called a microcontroller. Mikrokontrolere is an IC with a very high density, in which all the parts necessary for a controller has been packed in one chip, usually consists of:

Zilog Z80

Zilog Z80

  1. CPU (Central Processing Unit)
  2.  RAM (Random Access Memory)
  4. I / O, Serial and Parallel
  5. Timer
  6. Interrupt Controller

On average microcontroller has bit manipulation instructions, access to I / O directly and easily, and interrupt the process fast and efficient. In other words, the microcontroller is "single chip solution" that drastically reduce component count and design costs (the price is relatively low).

  • Applications Forum

Aside from being a home monitoring system as above, microcontrollers often
found in household appliances (microwave ovens, TVs, stereo sets, etc.), computers and equipment, cars and so forth. In some uses could be found in more than one processor in it.

microwave ovens

microwave ovens

The microcontroller typically used for equipment that does not necessarily require high processing speeds. Although there may be between us imagine for controlling a microwave oven using a Unix-based system, controlling the microwave oven can easily use the smallest microcontroller. On the other hand if we want to control the missile in order to chase the neighbor's dog always barks middle of the night, we will need a processor with a higher speed.

Special nature of the microcontroller is small in size, saving power and flexibilitasnya cause the microcontroller is suitable for use as the registrar / recorder of data in applications that do not require the presence of the operator.

  • Type That Can Be Selected

The microcontroller is available in several options, depending on the needs and abilities desired. We can choose a microcontroller 4, 8, 16 or 32 bits. Besides, there is also a microcontroller with serial communications capabilities, keyboard handling, signal processing, video processing etc.
