Infineon SAK-TC233L-32F200F 32-bit AURIX™ Microcontroller for High-Performance Automotive Applications
The rapid evolution of automotive systems—ranging from advanced driver assistance systems (ADAS) and electrified powertrains to connected vehicle technologies—demands microcontrollers that deliver exceptional computational performance, functional safety, and reliability. The Infineon SAK-TC233L-32F200F MCU, part of the AURIX™ TC23x family, is specifically engineered to meet these rigorous requirements, establishing itself as a cornerstone for next-generation automotive electronic control units (ECUs).
At the heart of this microcontroller lies a high-performance 32-bit TriCore™ CPU architecture, which uniquely combines the real-time capability of a microcontroller, the computational power of a digital signal processor (DSP), and the high-performance features of a reduced instruction set computing (RISC) processor into a single, cohesive core. This integration is critical for handling complex algorithms in applications like electric power steering (EPS), advanced braking systems, and battery management systems (BMS) for hybrid and electric vehicles (EVs).
A defining feature of the SAK-TC233L-32F200F is its unwavering commitment to functional safety. The microcontroller is designed to comply with the stringent ISO 26262 standard, supporting systems up to ASIL-D—the highest Automotive Safety Integrity Level. This is achieved through dedicated safety mechanisms, including hardware-based memory protection, error-correcting code (ECC) on memories, and a sophisticated Lockstep Core architecture. The lockstep core operates as a redundant checker core, continuously monitoring the main core for faults and enabling immediate reaction to ensure fail-operational or fail-safe behavior.

Furthermore, the device excels in real-time performance and connectivity. It features a rich set of peripheral modules, including multiple CAN-FD (Flexible Data-Rate) interfaces for high-speed in-vehicle networking, LIN channels, and fast Ethernet support. These are essential for seamless communication between sensors, actuators, and domain controllers within the vehicle. Its enhanced PWM timers and high-speed ADC modules provide precise control for power electronics, such as inverters controlling an EV’s traction motor.
To support data-intensive tasks, the MCU is equipped with integrated flash memory and RAM, ensuring fast and deterministic execution of code. Its robust design also focuses on security, incorporating hardware security modules (HSMs) to protect against cyber threats, a paramount concern in connected and autonomous vehicles.
In summary, the Infineon SAK-TC233L-32F200F AURIX™ microcontroller is a powerful, safe, and connected solution that empowers automotive engineers to develop more intelligent, efficient, and secure vehicle systems.
