The soul of automotive electronics, MCU inSemiconductor engineers play a key role in the world. Zhao's article delves into the wide application of automotive control chips, especially car-scale MCUS such as the ARM Cortex family. The performance parameters of these microcontrollers, such as operating voltage, main frequency, storage capacity and I/O interfaces, have special requirements for the four core domains of body, chassis, power and cabin.
Zhang Rui analysis, from the perspective of chip manufacturing, the root cause of chip shortage is the imbalance between supply and demand. In addition, the verification cycle of vehicle chips is long and the threshold is high, which puts higher requirements on the accumulation of production enterprises. According to statistics, so farIn the scale of the entire automotive industry in China, the share of imported chips reaches 90%, and even key system chips are monopolized by foreign countries, and the autonomy rate of other body electronic chips does not exceed 10%.And the more radical new force brands, often use a more complete ecological Android basic system, such as NIO and Xiaopeng, their systems are based on the Android underlying system development, can provide rich functionality, so as to further use the advanced vehicle chip computing power.
Wan Gang, chairman of the China Association for Science and Technology, said that with the electricity of new energy vehiclesThe sub-architecture changes from distributed to domain centralized architecture, and the intelligent operating system of new energy vehicles should be able to support the upgrade of the power electronics architecture, while compatible with vehicle chips, sensors, and application innovation. Taking history as a mirror and compatible with innovation, China's automotive industry needs to seize the key opportunities for the development of intelligent vehicles in the Chinese market and rapidly develop a new application framework.
And Horizon's Journey 5 series of high computing powerThe chip is also about to be mass-produced in 2023, and it seems that local companies have indeed broken the competitive barriers of car-scale chips, and may usher in a golden development period. Affected by the lack of core wave in 2021, mastering the core technology in the supply chain has become an industry consensus. Under the trend of software-defined automobiles, the main control chip and computing platform have become the core of the development of automobile intelligence.
In the field of power semiconductors, especially IGBT and SiC MOSFET and other fields, the entire competitive landscape is relatively good, like BYD Semiconductor in the field of power semiconductors has a long time of technology accumulationStara Semi and CRRC era all use industrial-grade technology and experience to march to the car gauge level, and China has the opportunity to achieve import substitution in the short term.
BYD Semiconductor will continue to be committed to using the advantages of vehicle manufacturing, break the downstream application bottleneck of domestic car gauge semiconductor, achieve basic product coverage of car gauge semiconductor core system applications, and win-win cooperation with industry peers, hand in hand to help the high-quality development of the new energy automobile industry.
BYD Semiconductor entered the MCU field in 2007, and launched the first generation of 8-bit car-gauge MCU chips in 2018. Byd's topCar gauge MCU chip, is also the first national production car gauge MCU chip. In 2019, BYD launched the first generation of 32-bit MCU chips. To date, BYD Semiconductor's car-scale MCU has been installed in more than 5 million vehicles, carrying more than 500,000 vehicles.
Journey 5 is the third generation of vehicle level products after the mass production of China's vehicle level artificial intelligence chips 2 and 3, with both large computing power and high performance. Performance advantage: A single chip AI computing power 128 TOPS, support 16 camera perception calculation, support automatic driving required multi-sensor integrationCoordination, forecasting and planning control needs. Computing performance 1283FPS, 30W power consumption, latency less than 60 ms.
Huashan No. 2 A1000 Automatic driving computing chip Huashan No. 2 A1000 series chip is currently the largest and most powerful automatic driving computing chip in the mass production stage, and has completed all the vehicle regulation certification and software supporting required for mass production.
On December 12, Xinchi Technology, a three-year-old car-gauge chip enterprise, announced some of its achievements. IHS Markit data show that by 2025, the global semiconductor market will exceed 400 billion yuan, and China's automotive semiconductor market will reach 120 billion yuan, more than the current realization.
On November 4, at the intelligent Automobile Industry Summit of the 2022 Hangzhou Yunqi Conference, Zebra Wisdom and the leading car gauge chip enterprise Xinchi Technology jointly released the intelligent cabin ecological platform, and the two sides will accelerate the push based on their respective products and advantagesEnter the cabin and mooring in one landing, build a chip AliOS version of the baseline, and accelerate the development of the intelligent automobile industry.
Mass production Xinchi's car gauge chip has achieved large-scale mass production, got more than 100 mass production points, and served more than 260 customers, covering more than 90% of China's car factories. On September 6, the "Fourth Global New Energy and Intelligent Vehicle Supply Chain Innovation Conference" sponsored by the China Electric Vehicle 100 Association was held, and Zhang Qiang, chairman of Xinchi Technology, delivered a keynote speech entitled "Put the 'core' to drive the future".
Some intelligent cabin semiconductor companies also have a certainScale, Nanjing Xinchi Semiconductor is one of them, its self-developed X9 series processor is designed for the new generation of automotive electronic cockpit automotive scale automotive chip, built with 64-bit ARMCortex-A55 core. According to the company, the X9 managed to reach 100KDMIPS, 300GFLOPS of 3D performance, 2TOPS of AI computing, and up to 8 FullHD displays.
Chip strength and challenge As a leader in smart car gauge chips, Chip Technology focuses on SoC processors and MCU controllers, covering intelligent cabin and intelligenceScale chip the whole industrial chain to attack hard.
In addition, Dongfeng also led 9 enterprises, universities, and scientific research institutions to jointly establish the Hubei automotive chip industry technology innovation consortium, from research and development to production, and promote the formation of domestic leading automotive chip industry chain. The e-car App provides sales, popularity, reviews, price cuts, new energy, measurement, safety, zero integration ratio, ownership and other list data. For more data, please visit the Bitcar App.
Since its establishment, core engine technology has been steadily growing and expanding, and has been focusing on the development and development of high-performance automotive gauge chips and solutionsAt present, we have mastered the intelligent cockpit core self-developed technology and are gradually completing various verification, and in December 2021, we first publicly released a new generation of 7-nanometer car-scale intelligent cockpit multimedia chip "Longying No. 1".
On October 22, the closed-door seminar of "Wind Core Plan" and the "China Car Valley" to help Dongfeng Automobile automotive scale chip field layout Negotiation meeting initiated and hosted by Wuhan Economic and Technological Development Zone China Merchants Bureau was successfully held in Shanghai, and the meeting was assisted by Shanghai Gesti Automobile.
