- The semiconductor memory solution by Infineon offers security and functional safety in a single NOR flash device
- It also enables faster time-to-market and reduced total-cost-of-ownership
Infineon Technologies has announced the addition of Semper Secure to its Semper NOR Flash memory platform. This step has enhanced the company’s expertise in providing memory solutions. Based on Semper NOR Flash’s proven and robust smart memory architecture, Semper Secure NOR Flash is a memory solution to combine security and functional safety in a single NOR flash device to deliver the security, safety and reliability required for the most advanced connected automotive, industrial and communications systems.
The proliferation of connected systems is driving the need for greater system security. Semper Secure NOR Flash provides a trusted solution to meet demanding requirements and protects critical system information. When a NOR Flash is placed outside of a processor, it becomes vulnerable to a variety of attacks. Thus, having a secured flash solution is especially important. Semper Secure is a NOR Flash solution that serves as a hardware root-of-trust to provide end-to-end protection. Additionally, the Semper Solution Development Kit enables easy system integration for faster time-to-market and reduce total-cost-of-ownership.
Robust and standardised
The Semper Secure NOR Flash family includes AEC-Q100 automotive-qualified devices with an extended temperature range of -40 degrees Celsius to +125 degrees Celsius, supports 1.8 V and 3.0 V operating ranges and is available in densities of 128 Mb, 256 Mb and 512 Mb. Semper Secure NOR Flash is designed and fully compliant to the ISO 26262 standard and is ASIL-B compliant, ready to be used in systems up to ASIL-D.
The in-built EnduraFlex architecture simplifies system design by enabling optimisation for high endurance or long data retention partitions. The devices are offered with Quad Serial Peripheral Interface (SPI), Octal SPI and HyperBus interfaces. The Octal and HyperBus interface devices are compliant with the JEDEC eXpanded SPI (xSPI) standard for high-speed x8 serial NOR Flash and offer 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. Our 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.”
“As flash moves outside of the host processor, it has grown increasingly important to find ways to secure embedded systems,” said Jim Handy, President of Objective Analysis. “Infineon’s approach to secure the flash memory itself when it can no longer be embedded within the MCU is a compelling architecture that offers design engineers more versatility.”
Infineon’s 256 Mb Semper Secure NOR Flash devices are sampling to lead customers now, with volume production expected during the second quarter of 2021.
