2026-01-16 16:52:51 Applications of Industrial-grade Storage Cards in Automotive Electronics: Reliability Requirements
Automotive electronics impose strict reliability requirements on industrial-grade storage cards, which must withstand temperature fluctuations, high vibration, strong electromagnetic interference, and power fluctuations. As automobiles become more electronic and intelligent, industrial-grade cards are widely used in T-BOXes, dashcams, infotainment systems, and ADAS (Advanced Driver Assistance Systems).
Temperature resistance requires compliance with AEC-Q100 automotive electronics certification, operating from -40°C to 125°C. This withstands summer high temperatures in vehicles and winter outdoor cold, adapting to rapid temperature changes without performance fluctuations.
Vibration resistance must meet ISO 16750 automotive standards, enduring multi-directional, high-frequency vibrations during driving. This ensures uninterrupted data reading/writing, fully recording vehicle operation data, fault codes, and ADAS scenario data.
Data security requires hardware write protection to prevent tampering with VIN and IMEI codes. OTP (One-Time Programmable) areas store unique vehicle identifiers and encryption keys. Performance-wise, fast read/write speeds (write speed ≥60MB/s) support OTA firmware updates, real-time positioning data storage, and high-definition video recording.
Additionally, industrial-grade automotive cards have strong electromagnetic shielding to resist interference from car audio, engines, and radars. They support wide voltage adaptation (9V-36V) to cope with automotive power fluctuations, ensuring stable operation in all driving conditions.
