* First, they are chip microcontroller 8051. Features of these chips generally it is integrated with the full functionality of a small microprocessor, very suitable for control oriented design. Ie in it include: the microprocessor, program memory and data, counters, pulse generators, the input-output port serial and parallel, control circuit breaker. * Second, they range 8051 controller along with other microcontroller families in general in recent years developed the following directions: * Reduce consumption of small lines. * Speed up work or xugng beat frequency of the CPU. * Reduced power voltage power supply. * You can extend the on-chip functions, extending to great design. These features lead to achieve two important features are: reducing power consumption and enabling real-time control Should real terms it is very appropriate application with the driver-oriented design. * Thirdly, microcontroller MCS-51 of them supported a rich instruction set should allow more flexibility in problem write control software program. * Fourth, memory capacity memory programs and data. * Finally, the MCS-51 chip attached to them is now used very common and is considered standard industrial designs available. On the other hand, through market survey components having 8051 chips is easy to open up possibilities for practical design.
