Infineon SAK-TC233L-32F200FAC: A High-Performance 32-bit AURIX™ Microcontroller for Demanding Automotive and Industrial Applications

The Infineon SAK-TC233L-32F200FAC is a member of the renowned AURIX™ TC23x family, representing a highly integrated and safety-critical 32-bit microcontroller designed to meet the rigorous demands of modern automotive and industrial systems. Engineered with a focus on performance, security, and functional safety, this MCU is an ideal solution for applications where reliability is non-negotiable.

At the heart of the SAK-TC233L-32F200FAC lies a powerful tri-core architecture based on the proven TriCore™ CPU. This multi-core design, featuring three independent 32-bit cores running at up to 200 MHz, delivers the substantial computational throughput required for complex control algorithms and real-time processing. The parallel processing capability enhances performance and is fundamental for implementing advanced safety mechanisms, including lockstep cores. This architecture allows one core to operate in lockstep with another, continuously comparing operations to detect and manage potential faults in real-time, a critical feature for ISO 26262 ASIL-D compliance.

Beyond raw processing power, this microcontroller is packed with dedicated hardware accelerators that offload demanding tasks from the CPU. This includes a hardware security module (HSM) for robust cybersecurity and data protection, which is paramount for connected vehicles and industrial IoT applications. Its rich set of peripherals, such as multi-channel ADCs, capture/compare units, and numerous communication interfaces (CAN FD, LIN, SPI, Ethernet), provides the connectivity and control needed to interface with sensors, actuators, and network gateways seamlessly.

The device’s design prioritizes functional safety, making it a cornerstone for systems like electric power steering, braking, airbag control, and advanced driver-assistance systems (ADAS). In the industrial realm, its robustness and precision are equally valuable for controlling industrial drives, automated guided vehicles (AGVs), and renewable energy inverters.
