Based on Infineon’s Semper NOR Flash’s smart memory architecture, Semper Secure NOR Flash provides the security, safety, and reliability needed for advanced connected automotive, industrial, and communications systems.

A secured flash solution is important when NOR Flash is found outside of the processor, which makes it vulnerable to a variety of attacks. Semper Secure serves as a hardware root-of-trust and provides end-to-end protection. The Semper Solution Development Kit allows easy system integration to quicken time-to-market and reduce total cost-of-ownership.

The Semper Secure NOR Flash family features AEC-Q100 automotive-qualified devices that can operate in the extended temperature range of -40 °C to +125 °C. The devices have 1.8-V and 3.0-V operating ranges, and come in densities of 128 Mb, 256 Mb and 512 Mb. Semper Secure NOR Flash is fully ISO 26262 and ASIL-B compliant. It is also ready to be used in systems up to ASIL-D. The EnduraFlex architecture allows the devices to be used configured with partitions for high endurance or long data retention. The devices feature Quad SPI, Octal SPI and HyperBus interfaces. The Octal and HyperBus interface devices are JEDEC eXpanded SPI (xSPI) compliant for high-speed x8 serial NOR Flash and feature a read bandwidth of up to 400 Mbps.

“Having a secured connected system is a top priority for customers focused on protecting information and maintaining system integrity,” said Sam Geha, Head of Infineon Technologies LLC Memory Solutions. “As systems increasingly rely on external NOR Flash to protect code and data in connected systems, the need for added advanced cryptographic security in memory is growing. The Semper Secure NOR Flash architecture adds to the already most functionally safe Semper products a secure subsystem to enable end-to-end persistent protection and efficiently protect a system from being compromised.”
