In addition, with the increase of body network ECUs in the field of automotive sensors, LIN bus communication is widely used, especially in systems such as automotive air conditioning and thermal management. Suzhou Naxin Micro (booth number: N2.2340), an excellent domestic signal chain chip and solution provider, has announced the launch of a single chip pressure sensor signal conditioning chip NSA (C) 9262 with a car standard LIN bus interface.

This product belongs to the NSA (C) 926XX series of automotive grade pressure sensor signal conditioning chip product series, supporting LIN bus physical interface communication mode, and can be widely used in various electronic control systems such as automotive air conditioning and thermal management systems, intake/exhaust management systems, fuel vapor management systems, and brake assist systems.

It is reported that each taillight driver and taillight ECU form an independent taillight network through the CAN-FD Light interface, which is very suitable for applications with large spatial spans (such as through type taillights) and high pixel digital dimming of taillight layouts.

Previously, car companies pursued a super large central control screen to reflect a sense of technology, gradually developing to be equipped with more advanced technology configurations, such as car engine systems and intelligent driving functions, starting from the underlying logic of the vehicle to consider intelligent solutions. As an innovative embedded SOC chip and solution provider, National Technology (booth number: N2.2439) showcased many solutions in the field of intelligent cockpit at the Shanghai Electronics Exhibition in Munich. Based on its N32G/N32L series, which won the 2021 China IC Design Achievement Award, including the 360 panoramic driving recorder of N32G452REL7, electric vehicle code table based on N32L436CBL7, and other solutions in terms of performance, power consumption It has obvious characteristics and advantages in terms of integration and other aspects.

It should be noted that a car requires the use of over a hundred universal MCUs, and the MCU market share in the automotive market has exceeded one-third of the global MCU market. However, the automotive industry's supply chain is currently under strain. In response, Polar Ocean Semiconductor (booth number: N2.2435), which focuses on the industrial field, has begun to actively layout its automotive electronics related business. Its newly released ARM based ®  Cortex ®- The industrial grade universal APM32F030x8 series MCU with M0+core has been applied in the field of automotive intelligent cockpit.

As the center of automotive computing decision-making, the implementation of domain controllers relies on the main control chip. The improvement of the computing power of the main control chip has become one of the core of automotive intelligent upgrading, and its structural form is upgrading from MCU to heterogeneous SoC chips. To support the high current power supply requirements of automotive domain controllers, especially autonomous driving domain controllers, ST has exhibited a series of power management chips STP801, STPM802, STPM098, and STSHB50. STPM801 is an ideal diode and reverse output protection controller with hot plug, soft start and combination protection. It is applicable to 12V and 24V systems. It is the basic device to ensure the correct and continuous operation of the auto drive system. 

On the other hand, the emergence of autonomous vehicles requires high-performance graphics processors such as LiDAR, cameras, and ultrasonic sensors to collect, interpret, integrate, and interpret systems, which puts higher demands on the power distribution system. Traditional 12V power distribution buses in cars are no longer capable of being pulled by small horses. Even with the Advanced Driver Assistance System (ADAS), the 12V electrical system is no longer able to provide the required energy. Therefore, both the current hybrid electric vehicles, pure electric vehicles and future autonomous vehicle need 48V systems to withstand high energy consumption loads. Vicor (booth number: N4.4100) stabilized voltage converter DCM3717, which can quickly deploy high-performance 48V power supply for its traditional 12V load, while significantly optimizing the size, weight, and efficiency of the power system, supporting the LV148 specification (48V vehicle standard) for pure electric and hybrid vehicles.
