Infineon SLE95050F2-0314: Secure and Flexible Automotive Security IC for Next-Generation Vehicle Access Systems

The evolution of vehicle access systems is accelerating, moving beyond traditional physical keys to sophisticated digital solutions like passive entry and start (PEPS), smartphone-based access, and over-the-air (OTA) updates. At the heart of this transformation lies the critical need for robust security. The Infineon SLE95050F2-0314 emerges as a pivotal solution, a dedicated security controller engineered to deliver uncompromising protection and exceptional flexibility for next-generation automotive applications.

This security IC is built upon a foundation of advanced hardware-based security. It features a high-performance cryptographic coprocessor that efficiently handles complex algorithms like AES-128, ECC, and SHA-256, ensuring secure communication between the key fob, the vehicle, and backend systems. The core of its defense is a certified Common Criteria EAL6+ (High) security platform, representing one of the highest levels of assurance available for commercial hardware. This certification guarantees that sensitive data, such as cryptographic keys and vehicle identities, are stored and processed in a highly secure environment, effectively shielded from both physical and remote attacks.

Flexibility is a cornerstone of the SLE95050F2-0314's design. It is tailored for a vast array of use cases, from classic remote keyless entry (RKE) and PEPS to the latest digital keys based on Bluetooth Low Energy (BLE), Ultra-Wideband (UWB), and NFC technologies. Its support for secure OTA updates is particularly crucial for the modern automotive lifecycle, allowing manufacturers to deploy new features and security patches throughout a vehicle's lifetime, thereby future-proofing the access system against emerging threats.

Furthermore, the chip is designed to meet the stringent requirements of the automotive industry. It operates reliably across a wide temperature range and is qualified according to AEC-Q100 standards, ensuring resilience in the demanding electrical and environmental conditions of a vehicle. Its low power consumption is also essential for key fob applications, enabling long battery life without compromising security performance.
