SEMPER™ NOR Flash
Architected and designed for functional safety
Every day, customers rely on systems that depend on our NOR Flash technology to store code and data. Your safety is our number-one priority, and failure is not an option. That's why all of our high-density SEMPER™ NOR Flash memory devices exceed automotive quality and functional safety requirements, and are engineered to last.

The SEMPER™ NOR Flash memory family is Infineon's high-performance, safe, and reliable NOR Flash solution that integrates critical safety features for a broad range of applications spanning automotive, industrial, communications, and more. With SEMPER™ NOR Flash memory, Infineon delivers the industry's fi­rst ASIL-B compliant and ASIL-D ready NOR Flash device.

Key Features:

• ASIL-B compliant and ASIL-D ready: Meets ISO 26262 standard for automotive functional safety
• IEC-61508 ready
• Endurance flex architecture: Multiple partitions each configurable to provide up to 25 years of data retention or 1+ million cycles endurance
• Diagnostics: SafeBoot and error checking to ensure safe and reliable operation
• Read bandwidth of up to 400 MB/s: High-performance to enable instant-on applications with XiP (eXecute in Place), for direct program execution from long-term storage instead of code shadowing to RAM
• Interfaces: Quad SPI and JEDEC xSPI-compatible Octal and HYPERBUS™
• Automotive grade: AEC-Q100 qualified and proven at extreme temperatures (-40°C to +125°C)
• Enhanced reliability: Supports ECC (SECDED) along with CRC protection over interface and memory data
• 10+ years supply and availability for long-life platforms
