AEC-Q100 is a standard developed by the Automotive Electronics Council (AEC) to ensure the reliability and quality of integrated circuits (ICs) used in automotive applications. This standard defines the test conditions, methods, and acceptance criteria that semiconductor devices such as microcontrollers, processors, memory ICs, power ICs, and other logic devices must pass, to be used in the automotive industry. It was established in the 1990s by Chrysler, Ford, and General Motors.

AEC-Q100 Temperature Grading Systems

AEC-Q100 standard categorizes ICs based on the operating temperature range

Grade	Operating Temperature Range
0	-40°C to +150°C
1	-40°C to +125°C
2	-40°C to +105°C
3	-40°C to +85°C
4	0°C to +70°C

Key Trends

Reliability for Autonomous and Electric Vehicles: The emerging rise of autonomous driving and EV powertrains demands higher reliability standards
New Packaging and Testing Protocols: As semiconductor integrations are becoming complex with new packaging methods, more precision is required to ensure long-term reliability.
