How important are automotive chips?
So, is this little "car chip" really so important to a car? In fact, to put it simply, a car chip is equivalent to our human "brain" for a car, which controls almost all "behaviors" of the entire car.
Especially now that cars are moving towards the era of intelligence, autonomous driving, digitalization and electrification, with the introduction of deep learning algorithms, the amount of data processing is increasing, and automotive chips have become particularly important for a car.
To give a simple example, everyone knows about tire pressure monitoring, but if you want to realize this function of the vehicle, you need a separate chip to support it to complete this monitoring task.
So now even an ordinary car has more than 40 chips, let alone those pure electric cars or cars with automatic driving functions.
Some ultra-luxury models have hundreds of chips. If there is a shortage of one chip, the production of the entire car will be affected.
Automotive chip is mainly divided into three categories
1. Functional chip
MCU is also called "micro control unit". If the electronic control system, infotainment system, powertrain system, vehicle motion system and other system functions in the car want to run normally, they need to use this type of functional chip. Among them, the most popular "automatic driving system" is also inseparable from functional chips.
2. Power semiconductor
Power semiconductors are mainly used in automotive power control systems, lighting systems, fuel injection, chassis safety and other systems. Traditional fuel vehicles generally use them in the fields of starting, power generation, and safety; new energy vehicles require a large number of power semiconductors to realize vehicle Frequent voltage conversion requirements, and the blessing of power semiconductors are also indispensable in many parts of electric vehicles.
3. Sensor
The automotive sensor is the input device of the automotive computer system. Its function is to convert the information of various working conditions in the running of the car, such as the speed of the vehicle, the temperature of various media, the operating conditions of the engine, etc., into electrical signals and send them to the computer. best working condition. Such as oxygen sensor, tire pressure sensor, water temperature sensor, electronic accelerator pedal position sensor and so on.
What are automotive chips used for?
Divided by function, automotive chips can be roughly divided into three categories. The first category is responsible for computing power and processing, such as AI chips for autonomous driving perception and fusion, and traditional electronic control units for engine, chassis, and body control. The second type is responsible for power conversion, such as power devices such as insulated gate bipolar transistors, and the third type is sensor chips, which are used for automatic driving, various radars, and airbag tire pressure detection. According to estimates, each car is equipped with about 1,600 semiconductors on average. These semiconductor devices are distributed in various equipment and systems of the car. It is the car chip that dominates their collaborative work, such as logic computing chips, memory chips, and microcontrollers. Cars are inseparable from various chips, ranging from tire pressure detection, system cameras, to vehicle controllers, automatic driving and controllers. It can be said that the intelligence of the car is the intelligence of the chip.

The semiconductor decade: A trillion-dollar industry
The global semiconductor industry is poised for a decade of growth and is projected to become a trillion-dollar industry by 2030. The semiconductor industry, which makes vital components for the technologies we all depend on, hit the headlines over the past year. And it wasn’t all good news. Supply shortages led to bottlenecks in the production of everything from cars to computers and highlighted how tiny chips are critical to the smooth functioning of the global economy. In many ways, our world is “built” on semiconductors. With chip demand set to rise over the coming decade, semiconductor manufacturing and design companies would benefit now from a deep analysis of where the market is headed and what will drive demand over the long term. As the impact of digital on lives and businesses has accelerated, semiconductor markets have boomed, with sales growing by more than 20 percent to about $600 billion in 2021. McKinsey analysis based on a range of macroeconomic assumptions suggests the industry’s aggregate annual growth could average from 6 to 8 percent a year up to 2030. The result? A $1 trillion dollar industry by the end of the decade, assuming average price increases of about 2 percent a year and a return to balanced supply and demand after current volatility. Amid megatrends that include remote working, the growth of AI, and soaring demand for electric vehicles, manufacturers and designers should now take stock and ensure they are best placed to reap the rewards. Assuming EBITA margins of 25 to 30 percent, current equity valuations support average revenue growth of 6 to 10 percent up to 2030 across the industry, analysis of 48 listed companies shows. Still, some companies are better placed than others, and growth in individual subsegments could range from as little as 5 percent to as much as 15 percent (exhibit). Drilling down into individual subsegments, about 70 percent of growth is predicted to be driven by just three industries: automotive, computation and data storage, and wireless. The strongest-growing segment is likely to be automotive, where we could see a tripling of demand, fueled by applications such as autonomous driving and e-mobility. The 2030 cost of semiconductor content in a Society of Automotive Engineers (SAE) Level 4 car with an electric drivetrain could be about $4,000 compared with $500 for an SAE Level 1 car powered by an internal-combustion engine. Accounting for just 8 percent of semiconductor demand in 2021, the automotive industry could represent from 13 to 15 percent of demand by the end of the decade. On that basis, the segment would be responsible for as much as 20 percent of industry expansion over the coming years. Growth of 4 to 6 percent in the computation and data-storage market could be fueled by demand for servers to support applications such as AI and cloud computing, the analysis shows. In the wireless segment, meanwhile, smartphones could account for the majority of expansion, amid a shift from lower-tier to mid-tier segments in emerging markets and backed by growth in 5G. What do these lessons mean for decision makers? Certainly, the outlook for the semiconductor industry looks bright, notwithstanding potential short-term volatility due to supply–demand mismatches, as well as a changing global economic and geopolitical outlook. With growth set to continue in the longer term, the task for industry leaders will be to focus strategically on R&D, factories, and sourcing, and to apply the lessons of the modeling to unlock areas of opportunity.
Chipmakers For Consumer Devices See Slowing Sales Ahead
Chipmakers exposed to personal computers, consumer electronics and Android smartphones have noted weakening demand in their second-quarter earnings reports. Meanwhile, other semiconductor stocks have posted beat-and-raise reports on the strength of enterprise computing, industrial and automotive chip demand. In the past week, Advanced Micro Devices (AMD), Power Integrations (POWI), Qorvo (QRVO), SiTime (SITM), Skyworks Solutions (SWKS) and Synaptics (SYNA) lowered their revenue outlooks for the third and fourth quarters based on softening consumer device sales. And last week, Intel (INTC) and Qualcomm (QCOM) cut their guidance for the same reason. Slowing sales of personal computers and Android smartphones were well understood heading into the second-quarter earnings season. However, continued strong sales of Apple (AAPL) iPhones helped to offset the slowdown for chipmakers such as Skyworks and Cirrus Logic (CRUS). Qorvo Hit By Weak Chinese Smartphone Sales Wireless-chip maker Qorvo has been hurt by declining sales of Chinese Android smartphones, including those from Oppo, Vivo and Xiaomi. Qorvo faces a "massive headwind" as Chinese smartphone makers work down large inventories of components, Needham semiconductor stocks analyst Rajvindra Gill said in a note to clients. "They now expect December to be the bottom for the Android market following aggressive inventory burns," Gill said. The weakness is in low and midrange Android handsets, not premium devices, he said. Some Semiconductor Stocks Doing Well Chipmakers with greater exposure to cloud computing, industrial and automotive chip markets have outperformed this earnings season. Semiconductor stocks in that camp include Lattice Semiconductor (LSCC), Microchip Technology (MCHP), Monolithic Power Systems (MPWR) and Rambus (RMBS). Those companies have delivered beat-and-raise quarterly reports this earnings season. Semiconductor stocks overall have perked up lately. IBD's semiconductor manufacturing group currently ranks No. 76 out of 197 industry groups that IBD tracks. Six weeks ago, it ranked No. 134. IBD's fabless semiconductor industry group ranks No. 94, up from No. 166 six weeks ago. Meanwhile, the Philadelphia semiconductor index, known as SOX, is down 22.6% year to date, vs. a drop of 13% for the S&P 500. The SOX includes the 30 largest semiconductor stocks traded in the U.S.
Automotive semiconductor lead times are not yet improving
Semiconductor availability continues to be challenging. The lead times for the automotive microcontrollers (or MCUs) that a year ago captured everyone's attention have improved slightly since February. However, analog chip lead times remain consistently elevated at nearly 4x the long-term average, close to peak levels within the context of the current semiconductor shortage. We believe analog supply will continue to cause difficulties within the automotive supply chain.
