About AURIX™ TC4Dx microcontroller family

For applications like sensor fusion and integration platforms (e.g. vehicle motion controllers) TC4Dx offers high performance with extended connectivity and AI capability. For such use-cases TC4Dx includes smart accelerators like the PPU with private scalar core and 256bit wide vector unit. The new security module CSRM (Cybersecurity Realtime Module) with 10x performance vs. TC3x HSM. TC4D also offers native support for virtualization via hypervisor which enables software with freedom from Interference.

For connectivity applications like Zone controllers and Gateways TC4Dx offers features for improved data routing and integration of functions from end-point ECUs. The optimized architecture with accelerators enables high throughput without main cores intervention through the Data Routing Engine (DRE) and Ethernet bridges for efficient data routing. TC4Dx also features a de-centralized security concept with Crypto Satellites (CSS) for offloading main security module.

AURIX™ TC4Dx features 
  • Large local memories for fast access to more data
  • HW routing engines & bridges
  • CSRM: high-performance securi-ty module with private CPU, memories & crypto accelerators
  • CSS: Distributed crypto and hash engines for secure CAN/Ethernet communication
  • Software backwards compatible with the AURIXTM TC3x MCUs
  • Strong SW partner ecosystem
AURIX™ TC4Dx Safety & Security and Audio features

AURIX™ TC4Dx Safety & Security

  • Safety architecture is compliant to ISO 26262 (ASIL-D support)
  • Cyber Security architecture is compliant to ISO/SAE 21434 and supports post quantum cryptograph

AURIX™ TC4x Audio features set overview

The AURIX™ TC4x family includes products like the TC4Z, TC48, and TC44, each offering different audio communication packages with I2S/TDM and mixer configurations. These systems support 8-to-1 PCM stream mixing with sample rates from 8 to 192 Kbps, and feature their own PLL for audio clock generation and TSN media clock synchronization. The subsystem fabric provides local DMA routing and access protection.

Designed for various applications, the TC4x family enhances automated driving with acoustic environment sensing and road condition analysis, integrates AVAS and active noise canceling in electric vehicles, and reduces speaker cable complexity in infotainment and telematics systems. Additional features include in-cabin communication, audio zones, telematics microphone arrays, and eCall connections, making AURIX™ TC4x a comprehensive automotive audio solution.
