Infineon Reaches 10 Billion Unit Milestone with Integrity Guard–Based Secure Controllers; Introduces New 32-Bit TEGRION™ SLC27G

Security controllers are essential to modern digital life, embedded in electronic passports, ID cards, payment systems, and smartphones to safeguard personal data and digital identities. Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has now surpassed 10 billion units shipped of its secure controllers built on the Integrity Guard architecture—a milestone reflecting widespread global deployment.

To stay ahead of escalating cyber threats, these controllers must meet stringent security standards. Integrity Guard first appeared over 15 years ago in the 16-bit SLE78 series and has since become the backbone of Infineon’s secure controller lineup. Designed to deliver robust protection through a dual-CPU architecture and hardware-based error detection, it forms the foundation of Infineon’s security portfolio.

Building on this legacy, Infineon has launched the TEGRION™ SLC27G, a new member of the Integrity Guard 32 family. This contactless dual-interface controller is optimized for next-generation secure identity, payment, and authentication applications. Powered by a 32-bit Arm® v8-M core and enhanced cryptographic features, TEGRION is engineered for high security, efficient performance, and seamless implementation.

By delivering long-term resilience and meeting emerging regulatory frameworks like the EU Cyber Resilience Act (CRA), TEGRION offers:

• Advanced Integrity Guard 32 architecture: dual 32-bit CPUs with independent self-tests and hardware error detection.

• Future-proof security: a robust update mechanism that supports new security standards and resists quantum-computing threats.

• Certification readiness: currently undergoing evaluation by Germany’s BSI with a goal of achieving Common Criteria EAL 6+ certification.

“With over 10 billion devices in field, Integrity Guard–based security controllers have become ubiquitous,” said Maurizio Skerlj, SVP of Infineon's Connected Secure Systems division. “In an era of increasing cyberattacks, digital transformation, and stricter regulatory landscapes, high-assurance security is more critical than ever. TEGRION SLC27G meets these challenges head-on.”

By scaling up its secure controller offerings and advancing the Integrity Guard architecture to 32-bit, Infineon underlines its sustained commitment to global security and the evolving needs of secure ID, payment, and authentication systems.
