Experience the next level of real-time safety and security performance with the AURIX™ TC4x microcontroller family

The AURIX™ TC4x Microcontroller (MCU) family represents Infineon's 3rd generation of automotive microcontrollers, renowned for their high performance, reliability, safety, and security, built upon over 25 years of experience in the automotive sector.

The MCU devices, built around the 32-bit TriCore™ ISA, combine the real-time capabilities of a microcontroller, the computational power of a digital signal processor (DSP), and the high-performance features of a reduced instruction set computer (RISC) load/store architecture. This unique blend of capabilities enables AURIX™ MCUs to provide superior performance, reliability and safety, making them an ideal fit for a wide range of demanding applications such as automotive systems, where high functional safety and increased computational power are essential. 

Some of these applications include the control of electrical and hybrid vehicles, transmission control units, chassis domains, braking systems, zone controllers, battery monitoring systems, advanced driver-assistance systems, and vehicle motion control, thereby supporting the trend towards autonomous, clean, and connected vehicles.

The AURIX™ TC4x family of microcontrollers offers state-of-the-art security and safety compliance, adhering to the stringent standards of ISO 21434 and ISO 26262. This includes secured connectivity and post-quantum cryptography support, making them future-proof and resilient to meet evolving market demands for robust and secured automotive and industrial applications.
