DUBLIN–(BUSINESS WIRE)–The “Automotive Microcontroller Unit (MCU) Industry Report, 2024” report has been added to ResearchAndMarkets.com’s offering.
With policy support, the localization rate of automotive MCU will surge.
Chinese electric vehicle companies are quickening their pace of purchasing domestic chips to reduce their dependence on imported ones and expedite the development of China’s semiconductor industry system. According to unofficial goals, the overall penetration rate of homegrown automotive chips will be increased to over 20% in 2025, and state-owned and private automakers are encouraged to buy homemade chips as priority. Amid the long mass production cycle of automotive MCUs and the extremely low localization rate for a long time, the policy support will help local automotive MCUs boom.
In January 2024, the Ministry of Industry and Information Technology released the Guidelines for the Construction of the National Automotive Chip Standard System, suggesting that: in 2025, more than 30 key automotive chip standards should be formulated to clarify the basic requirements concerning environment and reliability, electromagnetic compatibility, functional safety, information security and more, and the technical specifications for key products and applications including control, computing, storage, power and communication chips should be formulated to meet the basic needs for safe and reliable application and pilot demonstration of automotive chip products; in 2030, more than 70 automotive chip standards should be formulated. Favorable policies facilitate the development of Chinese automotive MCU vendors.
International giants gain first-mover advantages in automotive MCUs. Chinese vendors started with body control with relatively low safety requirements, and some leading companies also work to make layout in power/chassis, cockpit, and autonomous driving fields. Chinese vendors gradually improve their automotive MCU product line layout and narrow the gap with international tycoons in product performance.
Chinese automotive MCU vendors have made an all-round layout of low-, mid- and high-end products.
High-end automotive MCUs have always been monopolized by international giants. For example, Infineon has a monopoly in the autonomous driving field; NXP and Renesas prevail in the gateway and power/chassis fields.
In recent years, Chinese vendors have been vigorously laying out high-end automotive MCU products, and some of them such as SemiDrive, AutoChips have already made a foray into the high-end market.
In March 2024, SemiDrive further improved the E3 series and released E3119F8/E3118F4, targeting such application fields as body domain control, zone controllers, front-view all-in-one, and LiDAR. The new product uses ARM Cortex R5F CPU, and packs at most two independent 400MHz high-performance application kernels, with the main frequency of the information security kernel up to 200MHz. In terms of tool chain, SemiDrive supports IAR and Greenhills, adapts to the mainstream ARM debugger, and provides SDK/MCAL basic software support. Currently, SemiDrive is partnering with multiple Chinese and foreign AutoSAR vendors and working on BSW adaptation.
In current stage, SemiDrive’s products have covered high-end fields of zone control, chassis and intelligent driving.
AutoChips: In October 2023, it introduced AC7870x, its first multi-kernel high-frequency MCU that meets the ASIL-D functional safety level and is based on Arm Cortex R52 kernel. AC7870x is primarily applied in the fields of power chassis, “three electrics” for new energy vehicles, and zone controllers under new EEA. The company thus officially entered the high-end automotive MCU field.
Build an independent domestic chip supply chain.
From 2021 to 2022, automotive MCUs were difficult to buy, with soaring prices, which made Chinese automakers realize the importance of an independent supply chain system and also gave scope to China’s local automotive MCUs.
Application of automotive MCU in functional domains
Conventional automobiles need about 40-50 MCUs. As EEA gets upgraded, the MCU requirements of autonomous driving, cockpit, body & zone control, power, chassis, central computing and so on have also changed. MCU products head in the direction of high performance.
For autonomous driving domain control, mainstream MCU products include Infineon TC297X/397X Series and the latest TC4X Series, ST Stellar Series, Renesas RH850 Series, TI Hercules, and SemiDrive E3 Series.
Central supercomputing platforms have higher requirements on chips’ functional safety. For example, Leapmotor’s Four Leaf Clover central supercomputing platform adopts NXP S32G. Wherein, the Standard Configuration version adopts Qualcomm 8155 (3rd Generation Snapdragon Cockpit Platform) + NXP S32G (3 cores); the Medium Configuration version adopts Qualcomm 8295 (4th Generation Snapdragon Cockpit Platform) + NXP S32G (7 cores).
NXP S32G Family utilizes three 400MHz Arm Cortex-M7 cores, and provides support for different products according to cost requirements and application scenarios.
MCU core design trends include GPU, new storages, built-in HSM security components, etc.
Conventional MCU products mainly integrate eight components such as CPU, memory, I/O port, serial port, timer, interrupt system and special function register. The development of domain control architecture brings new demand for high-performance and high-security MCUs.
Furthermore with the increasingly high MCU performance, the difference between MCU and MPU becomes ever smaller. From some moves of international giants in current stage, it can be seen that crossover MCU or crossover MPU is a layout direction they head in. Putting some hardware only available in MPU into MCU not only realizes low power consumption, low cost and simplicity of MCU, but also enables applications that were enabled only by MPU in the past.
MCU’s graphics processing capabilities are being enhanced.
As vehicles pose ever higher requirements for image definition, zoomable maps, video play, etc., MCU vendors have begun to compete in graphics processing in recent year. International tycoons like ST, Infineon, Renesas and NXP have launched MCU products with GPU integrated. Chinese vendors such as GigaDevice and HPMicro have also been working to make layout.
For example, the new TRAVEOT T2G Cluster family of automotive microcontrollers (MCU) with a new graphics engine enables cluster, infotainment and cockpit systems with MPU like performance at MCU cost.
In terms of memory, the graphics engine within the MCUs minimizes the memory required for graphics processing by a factor of 3 to 5, resulting in lower power consumption and lower costs.
The requirements for MCU security are higher.
MCU is an important node in vehicle networks and interacts with other ECUs (electronic control unit) via communication protocols such as CAN (controller area network) bus or Ethernet. These communication protocols, if not encrypted or authenticated, will easily intercepted and tampered by attackers, leading to malicious vehicle control or other safety incidents.
MCU thus plays a critical role in automotive cybersecurity. To cope with increasingly severe cybersecurity threats, effective measures need to be taken to strengthen automotive cybersecurity. Major automotive MCU vendors are also vigorously deploying high-security MCU products.
