Semper™ Secure solution, do you know it?

What is the Semper™ Secure solution? What does it do? The acquisition of Cypress Semiconductor Corp. helps Infineon Technologies Company enhance its storage technology capabilities. Infineon has announced the launch of Semper Secure, further expanding its award-winning Semper NOR flash memory series. Based on the powerful intelligent storage architecture of Semper NOR flash memory, Semper Secure is the first storage solution that can combine information security and functional security in a single NOR flash memory device, providing the requirements for the most cutting-edge intelligent connected cars, industrial applications and communication systems. information security, functional safety and reliability.

The continuous popularity of networked systems has put forward higher requirements for system security. Semper Secure NOR flash memory can meet the stringent requirements and protect critical system information. Secure flash storage solutions are particularly important for external flash storage, which is more susceptible to various types of attacks. Semper Secure is the only flash storage solution that provides end-to-end protection through a hardware root of trust, while its development kit enables easy system integration, resulting in faster time to market and lower total cost of ownership.

Sam Geha, head of storage solutions at Infineon Technologies, said: “Secure networked systems have become a top priority for customers who value information protection and system integrity. As more and more networked systems are protected with external flash memory Code and data, storage devices urgently need to further improve encryption security. Our new Semper Secure NOR flash memory architecture adds an information security subsystem based on the extremely high functional security Semper product series to achieve end-to-end continuous protection , effectively ensuring that the system is not damaged.”

Jim Handy, President of Objective Analysis, said: "When flash memory is placed outside the main processor, it becomes particularly important to ensure the security of embedded systems. For situations where flash memory cannot be embedded in MCUs, Infineon's secure flash memory solution is A very competitive architecture. It has better versatility and can be chosen by design engineers.”

The Semper Secure NOR flash memory series is AEC-Q100 automotive qualified, supports operating temperatures from -40°C to 125°C and operating voltages from 1.8V to 3.0V, and is available in 128 Mb, 256 Mb and 512 Mb specifications. Semper Secure NOR flash memory is fully compliant with the ASIL-B level of the ISO 26262 standard and is available in ASIL-D level. Its EnduraFlex™ architecture enables high durability of partitions or long-term data retention, simplifying system design. Semper Secure NOR flash memory provides four-way serial peripheral interface (SPI), eight-way SPI and HyperBus™ interfaces. The eight-way and HyperBus interface devices comply with the JEDEC eXpanded SPI (xSPI) standard for high-speed x8 serial NOR flash memory and support up to 400 MBps read bandwidth.

Infineon's 256 Mb Semper Secure NOR flash memory device has already provided samples to some customers and is expected to enter mass production in the second quarter of 2021. The above is the analysis of Semper™ Secure solution, I hope it can help you.
