SAK-TC265D-40F200WBB: High-Performance Automotive Microcontroller for Advanced Embedded Systems

The rapid evolution of automotive systems, from advanced driver-assistance systems (ADAS) to electric vehicle (EVC) control and connected car technologies, demands microcontrollers (MCUs) that deliver exceptional computational power, reliability, and safety. The SAK-TC265D-40F200WBB from Infineon Technologies stands out as a premier solution engineered to meet these rigorous demands. This 32-bit TriCore™-based microcontroller is designed to serve as the computational heart of the most sophisticated and safety-critical automotive applications.

At the core of the SAK-TC265D-40F200WBB is the high-performance TriCore™ AURIX™ TC26xx microprocessor. This architecture uniquely combines a microcontroller, a DSP, and a RISC processor into a single core, enabling efficient handling of both control-oriented and signal-processing tasks. Operating at 200 MHz, it provides the substantial processing bandwidth required for complex algorithms and real-time data processing. The device is further enhanced by a floating-point unit (FPU), which accelerates mathematical computations essential for functions like sensor fusion, predictive modeling, and torque vectoring in electric vehicles.

A defining characteristic of this MCU is its unwavering focus on functional safety and security. It is meticulously designed to comply with the ISO 26262 standard, supporting systems up to ASIL-D—the highest Automotive Safety Integrity Level. This is achieved through advanced hardware safety features, including lockstep cores for critical tasks, which operate in parallel to immediately detect and manage potential processing errors. Built-in memory protection units, redundant peripherals, and comprehensive monitoring capabilities ensure operational integrity even in the harshest automotive environments.

Complementing its safety features are robust cybersecurity modules. As vehicles become more connected, protecting them from malicious attacks is paramount. The AURIX™ TC26xx family integrates hardware security modules (HSM) featuring hardware accelerators for cryptographic algorithms like AES, SHA, and RSA, providing a secure foundation for over-the-air (OTA) updates, secure boot, and vehicle-to-everything (V2X) communication.

The SAK-TC265D-40F200WBB is equipped with a rich set of peripherals tailored for automotive networking and control. It includes multiple CAN-FD (Flexible Data-Rate) interfaces, Ethernet TSN support for high-bandwidth communication, and a FlexRay™ controller. Its high-resolution timers and numerous ADC channels allow for precise control of electric motors, power converters, and actuator systems, making it ideal for domain control and centralized vehicle architectures.

ICGOODFIND: The Infineon SAK-TC265D-40F200WBB AURIX™ TC265 microcontroller is a powerhouse of performance, safety, and connectivity. Its blend of a high-speed TriCore™ CPU, top-tier ASIL-D functional safety compliance, and integrated hardware security makes it an indispensable component for developers building the next generation of intelligent, secure, and reliable automotive systems.
