ADC chip mainly look at two basic indicators, one is speed , one is accuracy resolution . As the name suggests, the speed represents the analog signal bandwidth of the ADC can convert the bandwidth, the bandwidth corresponds to the maximum frequency in the analog signal spectrum. Accuracy is a measure of the difference between the converted digital signal and the original analog signal. What is a high-end ADC chip? Simply put, it is an ADC chip that is different from the consumer electronics market. Primarily used in the military industry, aerospace, wired and wireless communications, automotive, industrial and medical instruments (MRI, ultrasound), etc. . Areas where process, performance, and reliability are critical.
Microsemi's main products are low-speed and high-precision ADC signal chain chips and high-reliability MCU chips. The main application areas are smart health, pressure touch, smart home, industrial measurement and microprocessors. The company is one of the few signal chain chip companies in China that can straddle the two main areas of analog and digital circuit technology, mastering the two main nodes of measurement and control of the global AIoT infrastructure and using them in conjunction with its own ADC and MCU technology that can provide AIoT devices with "Precision". Perception ADC + Precision Control MCU + Precision AI Algorithm" to realize a one-stop solution for signal chain ecological closed loop. Specifically, it includes: ① High precision ADC chips: by measuring real-world analog signals and converting them to digital; the rise of the Internet era requires that about 50% of the world's electronics ADC chips/modules are mainly used in areas with very high technical and performance requirements, while MCUs are used as the core of intelligent Control, and the CPU and memory integrated on the chip to form a chip-scale computer has become the basis of the information industry and industrial control. ② signal chain MCU chip: from measurement to calculation and then to control, the complete closed loop formation of the signal chain; Chipsea competition in the core value point mainly lies in high-precision sensing technology, reliability and high-reliability control technology, the company has accumulated a high-precision intelligence of the ion measurement ADC / AFE technology for many years, the latter from the company's accumulation of high-reliability MCU chip technology.
Core Ocean Technology's downstream customers include Xiaomi, Huawei, etc., the company will focus its resources on chip design and R & D, in order to improve the company's response efficiency to downstream customers; in terms of the distribution model: (intelligent medical chip sold to Xiaomi, Huami, Lexin, Xiangshan), Zhuoxin Micro (general-purpose microprocessor chips are sold to Wanmao acoustics), Wisecomm Technology and the CLP International Information Technology. The company's upstream procurement mainly focuses on chip manufacturing costs, and the company is a fabless IC design company that specializes in IC design, which helps it respond faster and better to changes in market demand. The company has established a stable relationship with Hua Hong Semiconductor, Tianshui Huatian, Ezra Micro, SMIC and other domestic professional IC manufacturing, packaging and testing companies to effectively ensure the chip production capacity.
Core Ocean Technology after 17 years of development, has broken the foreign monopoly on domestic high-precision ADC, is the current domestic high-precision chip 23.5 effective number of record-holders, and its 24-bit low-speed high-precision chip CS1232 differential input impedance as high as 5GΩ, the error of the temperature drift is as low as 0.5 ppm /, the resolution is more than one millionth, in the industry's high level. Its 24-bit, low-speed, high-precision chip CS1232 has a differential input impedance of up to 5GΩ, an error temperature drift as low as 0.5ppm/, and a resolution of more than 1 part in a million, which is the industry standard for similar chips. In the smart health chip, the company's representative products are mainly CS125X series chips (mainly used for body fat scale, infrared forehead thermometer, etc.). The main competitor is the international famous TI company. In the field of MCU chips, China's MCU market is relatively decentralized, CoreTech has a unique technical advantage and great potential, Currently, China's MCU market is still mainly occupied by foreign manufacturers, such as STMicroelectronics, NXP, and Renesas Technology. The top eight foreign MCU manufacturers account for 84.08% of the market. Although the domestic market is also like the Zhao Yi innovation, Zhongying Electronics and other MCU manufacturers stand out, but the overall market share is still relatively low, from the point of view of substitution of imports, the domestic MCU chip design companies still have a lot of room for improvement.
The highest level of MCU microcontroller chip is the current 32-bit products, mainly used in the field of power fast charging. The current 32-bit MCU products are mainly CS32G020 / 021 series, standard industrial products are Cypress CCG3PA series and ST's STM32G071K8 series. MCU chips have a wide range of applications, and the market size in the integrated circuit field is relatively large. Currently, the MCU market in China is still dominated by MCUs from foreign manufacturers such as ST (STMicroelectronics) and NXP (NXP). Domestic MCU chip design companies have a lot of room for improvement. There is no direct competition with the first-tier domestic companies, such as Zhao Yi Innovation and Zhongying Electronics, due to the different end-use areas. Zhao Yi innovation is mainly 32-bit applications in the Internet of Things, industrial control. In this field, the company's MCU chip is currently 8-bit, mainly used for electronic consumer products, 32-bit MCU products are currently mainly used in the field of power fast charging.
In the first three quarters of 2020, the company's operating income was 254 million yuan, a year-on-year increase of 66.88%; of which, in the third quarter of the operating income of 94 million yuan, a year-on-year increase of 59.49%, and net profit attributable to owners of the parent company of 61 million yuan, a year-on-year increase of 216.62%.
A-share listed semiconductor signal chain chip dark horse stock core sea technology since the listing to maintain the oscillation upward pattern, the main stage of control structure, according to big data statistics, profit-making chips about 95%, the main chip about 54%, the main control ratio of about 41%, trend research and multi-purpose research and judging can be referenced to the 15-day EXPMA and 35-day EXPMA.
The main purpose of this article is to provide a comprehensive overview of the main features of the semiconductor signal chain chip.
