（2） Main business
Chipsea Technologies (Shenzhen) Corp.Ltd(688595) is a full signal chain chip design enterprise integrating perception, calculation, control and connection. It focuses on the R & D and design of high-precision ADC, high reliability MCU, measurement algorithm and one-stop solution for the Internet of things. The company adopts fabless business model, and its chip products are widely used in smart health, smart phones, consumer electronics, wearable devices, smart home, industrial measurement, automotive electronics and other fields. The company's chip products can be divided into health measurement aiot chip, analog signal chain chip and MCU chip, as shown in the figure below:
Health measurement aiot chip mainly relies on artificial intelligence and Internet of things technology to apply highly integrated full signal chain chip to the field of health measurement. The company's health measurement aiot is an Internet of things system including chip + algorithm + big data. Its products include intelligent health measurement equipment, such as human composition analyzer, watch bracelet, etc.
The company's health measurement aiot chip takes ADC, MCU and ble / WiFi chip as the core basic hardware architecture, and combines the algorithm and big data capabilities to enable aiot innovation. Among them, the eight electrode human body composition analyzer can detect human body weight, body fat rate and other health status, wearable watches and bracelets can measure daily health data such as heart rate and blood pressure, okok app can obtain the detected health parameters, analyze human health status, and establish a prediction model for chronic diseases in combination with health big data and AI algorithm, Give suggestions on exercise, diet and sleep through app and other interactive means to reduce the risk of users' chronic diseases and achieve the purpose of health management, so as to form a complete solution.
The analog signal chain chip takes the company's high-precision ADC technology as the core to convert natural analog signals such as temperature, pressure, sound or image into digital signals for subsequent storage, processing and transmission. The company's analog signal chain chip has a wide range of application scenarios and is still expanding. At present, it is mainly used in battery management, pressure touch, smart home perception and industrial measurement. At the same time, it is also more and more widely used in downstream products such as environmental monitoring, automobile and other personal consumer electronics.
The company's MCU chip has been widely used in smart terminal fields such as mobile phones, personal computers, wearable devices and smart home control, as well as industrial fields such as industrial measurement, sensors, instruments, motor control and battery management system (BMS). The company has preliminarily completed the MCU development platform and realized the structured and modular development of MCU. On this basis, it has quickly launched a series of highly integrated MCU for different market segments to meet the wide needs from 8-bit to 32-bit, from low cost to high precision and high performance.
（3） Core technology and R & D level
1. Core technology
Chipsea Technologies (Shenzhen) Corp.Ltd(688595) is a full signal chain chip design enterprise integrating perception, calculation, control and connection. It focuses on the R & D and design of high-precision ADC, high-performance MCU, measurement algorithm and one-stop solution for the Internet of things. The company's current core technologies include high-precision ADC technology and high-reliability MCU technology.
China's technology in the field of high-precision ADC design is weak, and has always been monopolized by foreign countries. Before 2007, there were few enterprises focusing on high-precision ADC design in China, and the medium and high-end weighing instruments had high requirements for ADC accuracy. Therefore, the ADC chips used in China's medium and high-end weighing instruments in the early stage were mainly from foreign Ti, ADI and other global leading enterprises of ADC technology. After the mass production of CS1242 products of the company, the precision is as high as 24 bits and the effective digits are 21 bits, which can meet the requirements of high-precision ADC for medium and high-end weighing instruments in China, and can be gradually applied to medium and high-end weighing instruments. In 2011, the company launched a 24 bit low-speed and high-precision ADC chip cs1232, which has reached 23.5 bits in effective digits and a resolution of more than 1 / 10 million. It has reached a high level in the industry among the same types of chips and is currently at the leading level in the industry.
On the basis of low-speed and high-precision ADC chips, the company has also become the first enterprise in the industry to adopt micro pressure strain technology and mass produce pressure touch SOC chips, realizing independent innovation in pressure touch chip technology. The pressure touch SOC chip was released in 2016 and achieved mass production and generated revenue in 2017. In 2020, the company launched a new generation of human-computer interaction chip integrating pressure touch and capacitive touch. The accuracy of its ADC has been improved by two bits and the sampling speed has been increased by four times. It has been applied to Xiaomi's latest concept machine. At present, the company's pressure touch has been applied to many application scenarios such as mobile phones, TWS headphones, pressure pens, smart speakers and so on. As of the reporting period, the company's pressure touch solutions have been introduced into the products of well-known customers in vivo, Xiaomi, Zimi, Meizu, Nubia, black shark and other industries.
The company's MCU is mainly 8-bit MCU and 32-bit MCU. At present, 8-bit MCU is mainly used in small household appliances, electronic toys and some medium and low-end automotive electronic products. 32-bit MCU is mainly used for high-end applications. The company launched the first USB PD3 in 2018 0 32-bit MCU chip is mainly used in the field of power fast charging. Meanwhile, the company's vehicle specification level signal chain MCU has passed aec-q100 certification and has begun to be introduced into the new product design of automobile front loading enterprises.
At the end of the reporting period, the core technology and its advanced nature of the company are illustrated in the following table:
Technical name, main technology, advanced technology and contribution to technology upgrading of the industry.

There are many factors affecting the accuracy of ADC, including the range of input signal, noise and the use of discrete components to solve the problem of high-precision measurement
ADC related power supply voltage, etc. Through the research of chip architecture and the demand of sample and hold circuit, there are some problems such as insufficient precision and complex processing
1 high precision ADC products research, sampling switch research, etc., the company has improved the signal input range and reduced the problem. The company's ADC is highly integrated, self-adaptive, self-developed and mass produced, which reduces the noise of the chip, reduces the impact of power supply noise on the ADC, makes it more responsive, and the price is significantly higher than that of foreign products
The ADC can meet the needs of various application scenarios. The advantages of can help downstream manufacturers quickly improve
Increase the technical content of end products. At the same time
Forcing the price of overseas products to drop sharply and promoting
Into the rapid development of related industries.
High precision reference source is one of the cores of high precision measurement. The temperature system of the reference source is through second-order temperature compensation and dynamic device matching
2 the correlation number and stability of high-precision reference ADC directly affect the measurement accuracy. Through second-order temperature compensation and other technologies, the accuracy of reference source is improved. Self developed technologies such as dynamic device matching of mass production source products improve the temperature coefficient of reference, enhance the stable and improved measurement accuracy, and meet relevant applications
Qualitative, which makes the accuracy of various measurements higher. Market demand for high-precision measurement.
