Automotive Applications
Event Data Recorder (EDR)
Mandatory regulations (including Chinese GB 39732) require recording critical data before and after accidents. Our eMMC solutions enable high-frequency writing within milliseconds while ensuring data integrity during unexpected power outages.
Automated Driving Data Storage
Specialized storage system for autonomous driving that records vehicle "driving rights" transitions. Requires extended storage capacity to maintain operational status records for minutes or hours of driving data.
Advantages of Automotive Grade eMMC
Extreme Environmental Adaptability
Vehicle electronic systems operate under harsh conditions including wide temperature ranges, severe vibration, and electromagnetic interference. Automotive grade eMMC outperforms consumer-grade alternatives in these demanding environments.
Wide Temperature Range: Operates from -45°C to +105°C, adapting to scenarios from winter cold to summer engine compartment heat exposure. Consumer grade eMMC typically operates only from 0°C to +70°C, risking read/write failures and data loss at extreme temperatures.
Anti-Vibration and Anti-Impact: Features reinforced packaging design with impact-resistant BGA packaging that withstands vehicle bumps and road impacts, preventing chip damage. Consumer grade eMMC prioritizes cost efficiency with weaker anti-vibration capabilities.
Anti-Electromagnetic Interference (EMI): Incorporates built-in anti-interference circuits that resist strong electromagnetic interference from engines, motors, and onboard radar, ensuring stable data transmission.
