Vehicle grade chips refer to chips that meet the technical standards of vehicle grade and can be applied to automotive control.
Here are some introductions about it:
characteristic
-High reliability: The service life of automobiles is usually over ten years, and automotive grade chips need to operate stably within a temperature range of -40 ℃ to 125 ℃ or even wider. At the same time, it should be able to withstand mechanical stresses such as vibration and impact during the driving process of the car, and meet strict failure rate requirements, such as the failure rate requirement of ADAS chips reaching 10 or even lower defective products per million products.
-High safety: The chips for safety functional components such as airbags and anti lock braking systems in automobiles must have dedicated production lines certified by ISO 26262 functional safety to ensure that risks are minimized in the event of malfunctions.
-Long lifespan: The lifespan requirement for automotive grade chips can reach 15 years, far exceeding the 3-5 years for consumer grade chips.
classification
-Functional chips: such as MCU and SoC chips, responsible for computing power and control, used for vehicle control, autonomous driving, etc.
-Power devices, such as IGBT chips, are mainly used as power supplies and interfaces for new energy vehicle models, responsible for power conversion.
-Sensor chip: used for various radars, tire pressure monitoring, etc., responsible for sensing the environment.
Industry development status
China has become the world's largest automotive market, and the trend towards electrification and intelligence has led to a significant increase in the number of automotive chips, providing a scale foundation for the localization of automotive grade chips. However, domestic automotive grade chips still face problems such as small vehicle application scale, long certification cycle, low technological added value, and high dependence on upstream industries.
