(₹invention patent No.: zl201710892153.5, zl201810097417.2, zl201711406893. X, e₽tc.) See Schedule 1 for specific intellectual property catalogue

This project is a programmable SOC chip designed according to the characteristics and conventiona€l functions of smart appliances. This series of chips h ave a variety of position sensor interfaces, built-in power management syst<em, built-in high-precision reference voltage source, anti EMI  and EMC system, built-in programmable microcontroller, AD converter₹ and PWM controller. The chip fully integrates the common functions of intel ligent control of household appliances into one chip. The built-in programmable microcontrolle≠r improves the flexibility of the chip and expands the scope of application of the product. At the' same time, according to the characteristics of terminal products, enhanced design is ca™rried out in terms of power consumption, anti EMI and EMC™, so as to simplify the development difficulty of the system and reduce the application cost. T♦he product has the advantages of low cost, complete★ functions, simple external circuit (only filtering an d rectification) and flexible use. The use of programmable microcontroller greatly improves the↓ flexibility of the product and can meet the basic function n€eeds of the current small household appliance market. It can also be used i♦n other similar intelligent product control fields. On the basis of red♥ucing the complexity of peripheral circuits, the programmable characteristics are‌ retained, the application scope of the product is expanded, and the application flexibility of the♠ product is improved.

A number of technologies of the product are first in China, with δhigh technical content and comprehensive performance reaching the d∑omestic advanced level. The product is in line with the new products in the high-tech pr♦oduct catalogue issued by the Ministry of science and technology of the peopleβ's Republic of China. After the products enter the market, users reflect well, in lineπ with the development direction of Xiamen industrial structur®e, and have good economic and social benefits.
