Semper NOR Flash Memory

Fueling a New Era of Automotive and Industrial Innovation

Every day, customers rely on vehicles and systems that depend on our NOR flash technology to operate smoothly and prevent accidents. 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, functional safety requirements, and are engineered to last.

The Semper NOR Flash Memory Family is Cypress' newest high-performance, safe, and reliable NOR Flash memory solution that integrates critical safety features for automotive and industrial systems. With Semper NOR Flash Memory, Cypress introduces the industry's fi­rst ASIL-B compliant and ASIL-D-ready NOR Flash memory.


Semper NOR Flash Memory Architecture


Semper NOR Flash Memory Key Features

  • ASIL-B-Compliant and ASIL-D-Ready: Meets ISO 26262 standard for automotive functional safety
  • IEC-61508 Ready
  • EnduraFlex™ Architecture: Configure multiple partitions to provide up to 25 years of data retention and 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), which can execute programs directly from long-term storage instead of copying the code to RAM first
  • JEDEC xSPI-Compatible: Provides JEDEC xSPI-compliant Quad SPI, HyperBus, and Octal interfaces
  • Automotive Grade: AEC-Q100 qualified and proven at extreme temperatures (-40°C to +125°C)
  • Enhanced Reliability: Supports Single Error Correction and Double Error Detection (SECDED), Error Correcting Code (ECC), along with CRC protection over interface and memory data
