MCS-5 1 integrates all the main components of microcomputer on one chip, which greatly shortens the data transmission distance, improves the reliability and runs faster. As a microchip microcomputer, the layout and structure of each functional part in the chip have been optimized, the anti-interference ability has been strengthened, and the work is relatively stable. Therefore, in the industrial measurement and control system, the use of single chip microcomputer is the most ideal choice. Single chip microcomputer is a typical embedded system and the best equipment for low-end control system.

The development environment of MCS-5 1 is low and the software resources are very rich. Books and development software introducing its functions and characteristics can be seen everywhere. You only need to equip a PC (personal computer-there is basically no requirement for computer configuration) and a simulation programmer to realize product development. Most of the early development software used DOS version. With the popularity of Windows software, almost all of them now use the Windows version. And the variety of software is dazzling. Among many kinds of single-chip computers, C5 1 has the richest environmental resources, which brings great convenience to users of C5 1.
