The development of technology
Since the single-chip microcontroller technology has already appeared, through nearly 20 years of development. In 20 years development course, chip microcontroller technology development in microprocessor (MPU) technology and the large scale integrated circuit technology development as the forerunner, take the extensive application, showed a microprocessor more personalized trends.
SCM long life: here, on the one hand, the long life to develop products MCU can work stably and reliably ten or twenty years, on the other hand pared with the microprocessor to the long life. Along with the rapid development of semiconductor technology, MPU renewal faster and faster, with 386, 486, as a representative of the 45/79 MPU, very short time was eliminated, and traditional 8051 microcontroller as 68HC05, such already 15 years old age, production is still rising. This is due to its application of adaptability, on the other hand is due to such as the core, integrated with CPU more I/O modules of the new chip endless series. Can foresee, some essful listing of relatively young CPU core, as I/O modules ceaselessly, has a long survival period. A new type of CPU, make SCM team, give users more choices.
8, 16, and 32-bit mon development is the development of the technology of another. Long-term since, the microcontroller technology development is mainly eight
