Frequently Asked Questions (FAQ)
Why is ISO 26262 ASIL-B compliance important for automotive low-voltage ECUs?
Automotive low-voltage ECUs (e.g., for lighting or door locks) require safety certification to meet global carmaker standards-non-compliant MCUs need $4,800 external safety chips per design, adding $70k yearly for 15 designs. ASIL-B compliance eliminates external parts and cuts certification time by 3 months. An ECU engineer said: ??Our old non-compliant ECUs needed $4.8k safety chips-this ASIL-B model doesn??t. We saved $70k yearly and won a $1.0M contract with a major carmaker, launching 2 months ahead of competitors.??
How does 1.2mA active current benefit automotive sensor hubs?
Automotive sensor hubs run on 12V batteries-high-power (2.4mA) MCUs drain batteries 2x faster, leading to 20% more roadside assistance calls and customer complaints. 1.2mA active current cuts drain by 50%, extending battery life by 16%.
