Microcontroller can be likened to a computer that is in a special chip or a computer with a single chip.<\/span> The word ‘micro’ claim that a piece of equipment that is small and the word ‘Controller (controller)’ states that this tool is used to control one or more functions of an object, event or process.<\/span> This is also called an embedded controller, therefore mikrokontrolers is often embedded in the system (emmbedded System) or the equipment they control.<\/span><\/p>\n Microcontroller contains a simplified processor, some memory (RAM and ROM), Port I \/ O and peripheral equipment such as counters \/ timers, analog-to-digital and others are all integrated on a single chip.<\/span> This is the advantage of a microcontroller in which the processor and peripheral components available in a chip that differentiates the microprocessor-based system.<\/span> Examples of microcontroller ATMEL 89c51 \/ AT 89S51 \/ XX, ATMEGA 8535, 16 ATMEGA PIC, etc.<\/span><\/p>\n Block diagram of the microcontroller can generally be seen in the figure below:<\/span><\/p>\n Figure 10. Block Diagram of microcontroller<\/span><\/p>\n Similar to a microprocessor, microcontroller technology is developing very rapidly, conformed to the desires and needs of people, ranging from simple microcontrollers to complex resulting in one chip IC are ADC and DAC circuits.<\/span> With evolving technology using CISC or RISC architectures such as the AVR (Alf and Vegard RISC).<\/span><\/p>\n
