Infineon presents the next generation AURIXTM TC4x

First silicon available: Infineon further strengthens its leading position as automotive semiconductor supplier with the new generation “AURIXTM TC4x”

As a global leader in the automotive semiconductor market, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) continues its innovation trajectory to shape future mobility. The company today announced the expansion of its AURIXTM family of microcontrollers and the availability of the first samples of the new AURIX TC4x family of 28nm microcontrollers (MCUs) for next-generation eMobility, ADAS, E-Architectures /E automobiles and affordable artificial intelligence (AI) applications.

The new family provides an upward migration path for the company’s leading AURIX TC3x family of microcontrollers. It includes next-generation TriCoreTM 1.8, as well as scalable performance enhancements from the AURIX accelerator suite. This includes the new Parallel Processing Unit (PPU), a SIMD vector digital signal processor (DSP) that meets the requirements of various AI topologies. This can include use cases as diverse as real-time control and radar post-processing. The scalable family concept enables a common software architecture enabling significant platform software savings.

Targeting a wide range of automotive applications, including the high demand for functional integration into domain and zone-based E/E architectures, the AURIX TC4x supports both eMobility and the advancement of automated driving thanks to safety systems. Infineon’s AURIX TC4x offers enhanced connectivity, including advanced safety and security, to further extend the company’s automotive leadership in reliable electronics.

Additionally, new SOTA (Software Over the Air) features help meet OEM demands for a fast and secure car-to-cloud connection, enabling updates in the field, as well as in-use diagnostics and analysis. of the vehicle. The new family of microcontrollers supports high-speed communication interfaces such as 5 Gbit Ethernet and PCI Express®, as well as new interfaces such as CAN-XL and 10BASE T1S Ethernet. This increased network throughput and connectivity gives customers the performance and flexibility to implement new I/E architectures. “Our new AURIX TC4x family pushes the boundaries of automotive microcontroller usage for safe and secure processing,” said Thomas Boehm, senior vice president of automotive microcontroller at Infineon. “Its optimized architecture based on intelligent accelerators gives customers the real-time performance and network throughput they demand.

The new family of microcontrollers will once again establish themselves as the cornerstone of the automotive industry’s systems of the future. Given the increasing complexity of vehicles and the activation of AI implementations, special attention has been paid to the AURIX TC4x ecosystem to ensure rapid time to market and ease of use. Infineon is collaborating with Synopsys to accelerate software development for the AURIX TC4x family. The Synopsys VirtualizerTM Development Kit (VDK) for TC4x enables software development much earlier in the design cycle. Synopsys DesignWare® ARC® MetaWare Toolkit for AURIX TC4x provides optimal compilers, debuggers and libraries as well as a simulator needed for software development for the PPU.

“Building advanced automotive systems to meet stringent safety features requires the implementation of artificial intelligence technology using both hardware and software,” said John Koeter, senior vice president of marketing and intellectual property strategy at Synopsys. “Our collaboration with Infineon to provide the DesignWare ARC MetaWare Toolkit and VDK for AURIX TC4x helps Infineon customers develop AI-driven features in the AURIX TC4x for applications such as powertrain and ADAS processing that meet safety, performance and energy efficiency requirements.”

More partner offerings will follow, and MATLAB support will be available for automatic code generation to enable rapid prototyping. Customers already implementing existing AURIX microcontrollers will benefit from accelerated time to market thanks to the scalable multi-generation family concept. Extensive hardware and software compatibility enables extensive reuse of customers’ existing TC3x algorithms and ecosystem.

The AURIX TC49x is currently being sampled at select customers, with production expected to begin in the second half of 2024. The DesignWare ARC MetaWare Toolkit for AURIX and Virtualizer Development Kit for TC4x are available now from from Synopsys.
