The main difference is the difference in service life, external environment and security.
The service life of the car gauge chip is longer than that of the mobile phone, and the service life of the mobile phone is generally four or five years. The temperature range of the car gauge chip is generally between -40°C and 150°C, while the mobile phone chip only needs to meet the working environment of 0°C to 70°C. The security of the car gauge chip is much stronger than that of the mobile phone chip, including functional safety and information security, and the data verification of the car chip is more stringent to prevent security risks.

According to typical application scenarios, the chip can usually be divided into four grades: consumer grade, industrial grade, vehicle gauge level and military grade, and its requirements are military > in turn. Car regulations > Industry > Spend.

Among them, the mobile phone chip belongs to the consumer level, the car chip belongs to the car regulation level, the application scenario of the mobile phone chip and the car chip is different, the focus of the design side is not the same, the car chip requirements are higher than the mobile phone chip.
Mobile phone chips are more technical than car chips, and the production process is more demanding! Mobile phone chips have entered the 5nm era, and cars are far from reaching!
