Frequently Asked Questions

What is AEC-Q100 qualification?

AEC-Q100 is the automotive standard for integrated circuit qualification. It includes: 1) Temperature grade classification (Grade 0: -40 to +150C, Grade 1: -40 to +125C). 2) Accelerated life testing (HTOL, temperature cycling). 3) ESD and latch-up testing. 4) EMC compliance. 5) Process capability studies. AEC-Q100 qualified parts meet strict automotive reliability requirements and are accepted by major OEMs.

Always specify AEC-Q100 qualified parts for automotive applications. Contact us for qualification documentation.

What is the difference between automotive and industrial grade?

Automotive grade includes: 1) AEC-Q100 qualification with full testing. 2) Wider temperature range (-40C to +125C vs -40C to +85C). 3) Enhanced screening and traceability. 4) PPAP documentation support. 5) Long-term supply commitment. 6) Zero defect quality targets. Industrial grade is suitable for commercial and industrial applications but does not meet automotive standards. For automotive, always use automotive-grade parts.

Use automotive grade for any automotive application, even for non-safety systems.

How do I implement secure boot?

Secure boot implementation: 1) Store root of trust in hardware security module. 2) Cryptographically sign firmware images. 3) Verify signature before execution. 4) Use secure storage for keys. 5) Implement rollback protection. 6) Enable debug port security. UNISemicon NOR Flash supports secure boot with hardware write protection and authentication features. Work with our FAE team for secure boot architecture design.

Contact our FAE team for secure boot implementation guidance and reference designs.

What is the supply commitment for automotive parts?

UNISemicon provides 15+ year supply commitment for automotive-grade products. This includes: 1) Product longevity program. 2) Last-time-buy notifications. 3) Form-fit-function compatible replacements. 4) PCN (Product Change Notification) process. 5) End-of-life management. This ensures supply continuity for automotive production and service requirements. Contact us for specific product lifecycle information.

Request product lifecycle documentation for your automotive project planning.

What documentation is available for automotive customers?

Automotive documentation includes: 1) AEC-Q100 qualification reports. 2) PPAP (Production Part Approval Process) documentation. 3) Reliability reports with FIT rates. 4) EMC test reports. 5) Material composition reports (RoHS, REACH). 6) Process capability studies. 7) Change notification agreements. This documentation supports automotive customer quality requirements and OEM approval processes.
