Infineon SAK-TC397XX-256F300S 32-bit AURIX™ TC3xx Microcontroller for High-Performance Automotive and Embedded Applications
The Infineon SAK-TC397XX-256F300S is a flagship member of the AURIX™ TC3xx microcontroller family, engineered to meet the rigorous demands of next-generation automotive and embedded systems. Combining exceptional processing power, advanced security features, and robust functional safety capabilities, this MCU is designed to serve as the computational backbone for applications where reliability, performance, and integration are non-negotiable.
At the heart of this microcontroller lies a high-performance 300 MHz TriCore™ CPU system with six independent cores. This multi-core architecture enables parallel processing, which is critical for running complex applications such as domain control, electric vehicle powertrains, advanced driver-assistance systems (ADAS), and autonomous driving functions. The parallel execution ensures that safety-critical tasks are isolated and processed without interference, providing a deterministic response essential for real-time control.
A standout feature of the SAK-TC397XX-256F300S is its compliance with the ISO 26262 functional safety standard, supporting systems up to ASIL-D—the highest automotive safety integrity level. This is achieved through hardware-based safety mechanisms including redundant computing units, built-in self-test (BIST) capabilities, and error correction codes (ECC) on memories. These features are vital for applications where system failure is not an option.
The device is further equipped with 2560 KB of embedded flash memory and 720 KB of RAM, providing ample space for code and data storage in sophisticated software environments. This is complemented by a rich set of peripherals including CAN-FD, Ethernet TSN, and FlexRay interfaces, making it ideally suited for connected car architectures and in-vehicle networking.
Security is another cornerstone of its design. With hardware security modules (HSM) featuring advanced encryption and secure boot capabilities, the microcontroller protects against cyber threats, ensuring the integrity and confidentiality of data—a must for vehicle-to-everything (V2X) communication and over-the-air (OTA) updates.
In addition to automotive uses, this MCU is also well-suited for industrial applications such as robotics, renewable energy control, and high-reliability embedded systems where functional safety and processing performance are equally critical.
