Overview

Infineon’s AURIX™ TC4x family of microcontrollers - a leader in real-time safety and security performance is coming!

Major disrupters have emerged in the automotive market:

  • innovation in automotive E/E architecture microcontrollers (MCUs) in the areas of domain and zone control
  • accelerated shift from conventional powertrain to xEV
  • increased safety and automated driving

Infineon’s AURIX™ TC4x family addresses these challenges, pushing the boundaries in automotive MCU usage for safe and secure processing. These microcontrollers are designed for next generation eMobility, ADAS, automotive E/E architectures and affordable artificial intelligence (AI) applications. The first AURIX TC4x samples have already been chosen by lead customers for their upcoming designs.

The new scalable microcontroller TC4x family provides an upward migration path from Infineon’s leading AURIX™ TC3x family of ASIL-compliant automotive MCUs. Performance is boosted by the next-generation TriCore™ 1.8 and the scalable AURIX™ accelerator suite, including the new PPU (Parallel Processing Unit) and multiple smart accelerators.

Support for high-speed communication interfaces like 5G-bit Ethernet and PCIe along with new interfaces such as CAN-XL and 10BASE T1S Ethernet gives customers the performance, throughput and flexibility needed to implement new automotive-specific microcontrollers with E/E architectures.

The scalable family concept enables a common software architecture supporting significant platform software savings and the feature-rich concept gives plenty of headroom to grow for both Tier 1’s and OEMs.

The AURIX™ TC4x family features audio capabilities with I2S/TDM and mixer configurations, supporting 8-to-1 mixing of PCM streams at sample rates between 8 and 192 kbps. It includes a dedicated PLL for generating audio clocks and tunable frequencies for TSN media clock synchronization. The subsystem enables local DMA routing of mixer output with access protection.

Designed for applications like automated driving, the TC4x supports acoustic environment sensing for siren detection, road user identification, and surface analysis. In electric vehicles, it integrates AVAS and in-cabin active noise canceling. For infotainment and telematics, it offers audio amplification in zonal modules, reducing cable complexity and weight, while supporting in-cabin communication, audio zones, and telematics microphone arrays.
