AURIX™ TC4Dx microcontroller  is the first member of the latest AURIX TC4x family.  Based on 28nm technology, the AURIX TC4Dx offers increased performance and high-speed connectivity.

AURIX™ TC4Dx offers 6/6 lockstep cores at 500 MHz, up to 20 MB non volatile memory in eFlash technology, 10 MB SRAM and rich connectivity features including two 5 Gbps and four 10/100 Mbps Ethernet interfaces.

For applications like sensor fusion and integration platforms (e.g. vehicle motion controllers), AURIX™TC4Dx offers high performance with extended connectivity and AI capability. For such use-cases AURIX™ 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. AURIX™ TC4D also offers native support for virtualization via hypervisor which enables software with freedom from Interference.

For connectivity applications like Zone controllers and Gateways AURIX™ 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.

To address the need for high speed communication & new interfaces, AURIX™TC4Dx features a rich connectivity set:

• up to 2x 5Gbit Ethernet incl. bridge
• 4x 10/100Mbit Ethernet
• 20 CAN nodes
• 4x CAN-XL 
• up to 2x 8 Gbit PCIe 3.0.

In order to ensure the scalability, the whole TC4x family shares its core architecture (TriCore™ based), allowing a maximum of software re-use, but also offers pin compatibility on two main packages (BGA-292 and BGA-436). With this approach, customers can develop on this AURIX™ TC4Dx for high end application and build a complete portfolio ECU with lower end devices.

Its holistic approach to functional safety meets the highest functional safety requirements according to ISO26262 ASIL-D. The AURIX™ TC4Dx also fulfills latest cyber security standards according to ISO/SAE21434 including post-quantum cryptography support.

Scalable to the entire AURIX™ TC4x portfolio, expanding across multiple applications, the TLF4x OPTIREG™ PMIC, next generation of functional safety power supplies will enable a seamless power supply design for the entire TC4x product portfolio.
