market expectation
With the development of technology, more and more non-traditional home appliances have emerged. Today, intelligent cleaning robots are gradually entering our home. At present, various household cleaning robots such as sweeping robots and vacuuming robots are selling online. According to industry experts, the current domestic auxiliary robots appear in our lives with an annual growth rate of more than 10%. Moreover, according to the industry data provided by it, the market space for home-assisted robots is at least over 100 billion yuan.
Project Introduction
The sweeping robot described in this paper has the ability to detect obstacles, automatically plan the walking route and cleaning area, and has a certain intelligent design. It can carry out seven-day scheduled cleaning and automatic charging. The specific performance is to be able to clean the room on time at the time set by the user. When the work is over or the power is insufficient, the charging stand can be automatically searched for charging, and no manual command is required. The movable body of the fuselage is an automatic technology, and the vacuum cleaner with a dust box, with the body setting control path, repeatedly walking indoors, such as cleaning along the side, concentrated cleaning, random cleaning, straight cleaning, etc. It is supplemented with side brush, central main brush rotation, rag and other methods to enhance the cleaning effect to complete the anthropomorphic home cleaning effect. In order to achieve intelligence, a high-precision, high-reliability real-time clock system is required. The Epson RTC RX8010SJ from Shiqiang has won customer projects with its high precision, high integration and low power consumption.

Technical parameters and technical difficulties
1. High precision
Integrate c into the RX8010SJ to ensure the clock accuracy of the entire system.
2. High integration
The 32.768K RX8010SJ peripheral does not require a matching circuit and can be hung directly on the main chip.
3. Low power consumption
The RX8010SJ has a very low power consumption of 160nA.
Advantages of Epson RTC
High precision, built-in 32.768K, customer engineers do not need matching circuits in the design process, directly hung on the main chip, saving time for subsequent debugging. Compared to the external crystal oscillator, the Epson RTC product with built-in crystal structure has a small number of components, which makes the overall design of the product more compact. The miniaturization and high reliability of the clock chip are realized. There is no need to consider the layout and routing of the external crystal oscillator. The built-in crystal RTC products are all packaged in a chip package, which improves the production efficiency and quality of the product.
Epson crystal oscillators have made major breakthroughs in 32.768KHZ, MHZ, and GHZ, making Epson's crystal components ranked first in the industry with 23% market share. Epson makes full use of its own advantages and applies "QMEMS" technology that combines quartz materials with "MEM". Crystal products have high precision, small size, high stability and low power consumption, making Epson clock products in communication systems. Widely used in fields such as intelligent devices.
