Technical requirements and market status of automotive-grade chips

Automotive-grade chips have very high requirements for performance indicators, service life, reliability, safety, and quality consistency, which are difficult to match for consumer electronic chips. The working environment is harsh, with a temperature range of -40℃~155℃, high vibration, a lot of dust, electromagnetic interference, etc. Due to personal safety issues, automotive chips have higher requirements for reliability and safety, and the general design life is 15 years or 200,000 kilometers. At present, there are not many companies in the world that can produce automotive-grade chips, such as NXP, Infineon, Siemens, etc.
