Acquisition of Cypress Semiconductor Corp. helps Infineon Technologies Company enhance its storage technology capabilities. Infineon Technologies has announced the launch of Semper Secure, further expanding its proven Semper NOR Flash memory family. Based on the powerful intelligent storage architecture of Semper NOR Flash, Semper Secure is the first storage solution that can combine information security and functional safety in a single NOR Flash device, providing the required information security, functional safety and reliability for the most cutting-edge intelligent connected vehicles, industrial applications and communication systems.

The increasing popularity of connected systems has put forward higher requirements for system security, and Semper Secure NOR Flash can meet the stringent needs to protect critical system information. For external Flash memory, which is more vulnerable to various attacks, secure Flash solutions are particularly important. Semper Secure is the only Flash solution that can achieve end-to-end protection through hardware root of trust, and its development kit can easily achieve system integration, thereby accelerating time to market and reducing total cost of ownership.

“Secure connected systems are a top priority for customers who value information protection and system integrity,” said Sam Geha, head of memory solutions at Infineon Technologies. “As more connected systems rely on external flash to protect code and data, there is a need for storage devices to be more cryptographically secure. Our new Semper Secure NOR Flash architecture adds a security subsystem to the already highly functionally safe Semper product family, providing end-to-end continuous protection that ensures systems cannot be compromised.”

“When Flash is placed outside the main processor, it becomes even more important to ensure the security of the embedded system,” said Jim Handy, President of Objective Analysis. “Infineon’s Secure Flash solution is a very competitive architecture that provides greater versatility and choice for design engineers when Flash cannot be embedded in the MCU.”

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 fully complies with the ASIL-B level of the ISO 26262 standard and can be used for ASIL-D level. Its EnduraFlex™ architecture enables high durability or long-term data retention in partitions, simplifying system design. Semper Secure NOR Flash memory provides quad serial peripheral interface (SPI), octal SPI, and HyperBus™ interfaces. The devices with octal and HyperBus interfaces comply with the JEDEC eXpanded SPI (xSPI) standard for high-speed x8 serial NOR Flash memory and support read bandwidths of up to 400 MBps.

Infineon’s 256 Mb Semper Secure NOR Flash devices are already sampling to select customers and are expected to be available in volume production in the second quarter of 2021.
