The MCU is the first member of the latest AURIX TC4x family and based on 28nm technology, the AURIX TC4Dx offers increased performance and high-speed connectivity.
The device combines power and performance enhancements with the latest trends in virtualization, Artificial Intelligence, functional safety, cybersecurity, and networking functions helping to pave the way for new Electric/Electronical (E/E) architectures as well as the next generation of software-defined vehicles.
These types of MCUs are considered crucial to control and monitor a wide variety of systems in the automobile such as vehicle motion control, Advanced Driver Assistance Systems (ADAS) and chassis.
“Microcontrollers like our new AURIX TC4Dx are the backbone of software-defined vehicles and are essential to further improve vehicle performance, safety and comfort.” said Thomas Boehm, Senior Vice President for Microcontrollers at Infineon. “The AURIX TC4Dx will contribute to secured processing performance and efficiency, and our customers will benefit from faster time-to-market and lower total system cost.”
The AURIX TC4Dx features an advanced multi-core architecture with the new 500MHz TriCore with six cores, all with lock-steps for highest functional safety performance.
With its Parallel Processing Unit (PPU), the MCU provides a platform for developing embedded AI-based use cases such as motor control, battery management systems or vehicle motion control. The MCU is supported by a strong software ecosystem and includes networking accelerators to boost Ethernet and CAN communication, as well as the latest interfaces such as 5 Gbit/s Ethernet, PCIe, 10Base-T1S and CAN-XL.
According to Infineon, this increased networking throughput and connectivity gives customers the performance and flexibility needed to implement E/E architectures and it holistic approach to functional safety meets the highest functional safety requirements according to ISO26262 ASIL-D.
The AURIX TC4Dx also full-fills the latest cyber security standards according to ISO/SAE21434 including post-quantum cryptography support.
The AURIX TC4Dx is currently sampling and will go in mass production in 2025.
