Infineon's 32-bit, AURIX TC4Dx TriCore-based system-on-chip (SoC) targets demanding ASIL D automotive applications (see figure). This includes software-defined vehicles (SDVs) that can take advantage of the six TriCore cores that run in lockstep. along with the additional accelerators. The SoC addresses a range of applications, such as chassis and advanced driver-assistance systems (ADAS).
The AURIX TC4Dx incorporates six 500-MHz TriCore cores. There's also a parallel processing unit (PPU) SIMD vector DSP that takes on artificial-intelligence and machine-learning (AI/ML) chores. They handle real-time applications such as battery-management systems (BMS), vehicle motion control and motor control, as well as chassis support. The low-latency interconnect (LLI) is designed to tie the high-resolution PWMs and eGTM timers with the PPU. The built-in analog-to-digital converter (ADC) is paired with the DSP accelerator.
Interfaces include 5-Gb/s Ethernet and CAN-XL. The 10Base-T1S single-pair Ethernet support provides high-speed, low-overhead peripheral support. The SoC also supports PCI Express (PCIe).
The SoC meets ISO 26262 ASIL D functional-safety requirements as well as cybersecurity standards like ISO/SAE21434, including support for post-quantum cryptography standards.
