Throughout the past 20 years of SCM Exhibition history we can see that the SCM technology to the development of the microprocessor (MPU) technology and ultra-large-scale integrated circuit technology for the Exhibition for the pilot to pull a wide range of applications, showing more personality than the microprocessor trend of development： SCM long life here said the long-life, on the one hand refers to the development of SCM products can be stable and reliable work 10, 20, on the other hand refers to the microprocessor compared to the long life. With the rapid development of semiconductor technology, MPU replacement faster, to 386,486,586 as the representative of the MPU, within a very short time to be out of Bureau, and the traditional microcontroller as 68 HC05, 8051, and so has been 15 years of age, the output is still rising. This is from Its application to the corresponding areas of adaptation, on the other hand is due to such CPU as the core, integrated with more I / O functions SCM module of the new series emerging. It is expected that the successful listing of the relatively young core CPU, also with the The I / O modules of the rich, have a long life cycle. New types of joining the CPU, the SCM team Has grown to the user brings more choice.  8, 16, 32-bit microcontroller common development this is the current SCM technology development trends of the other. For a long time, single - Machine technology is the development of eight-oriented. As mobile communication, network technology, multimedia technology, and other high-tech products Access to family, 32-bit microcontroller applications have been developed by leaps and bounds. 以Motorola Motorola 68K for the CPU to the 32 of the 97 SCM August sales of 10 million. That because of the pa
