About

For next-generation eMobility, ADAS, automotive E/E architectures & AI

Major disrupters have emerged in the automotive market:

  • Innovation in automotive E/E architecture MCUs in the areas of domain and zone control
  • Accelerated shift from conventional powertrain to xEV
  • Increased safety and automated driving

Infineon’s AURIX™ TC4x family addresses these challenges, pushing the boundaries in automotive MCU usage for safe and secured processing. These microcontrollers are designed for next-generation eMobility, ADAS, automotive E/E architectures, and affordable artificial intelligence (AI) applications.

AURIX™ TC4x family: A boost in performance

The new scalable microcontroller TC4x family provides an upward migration path from Infineon’s leading AURIX™ TC3x family of ASIL-compliant automotive MCUs. Performance is boosted by the next-generation TriCore™ 1.8 and the scalable AURIX™ accelerator suite, including the new Parallel Processing Unit (PPU) and multiple smart accelerators.

Support for high-speed communication interfaces such as 5G-bit Ethernet and PCIe along with new interfaces such as CAN-XL and 10BASE T1S Ethernet gives customers the performance, throughput, and flexibility needed to implement new automotive-specific microcontrollers with E/E architectures.

The scalable family concept enables a common software architecture supporting significant platform software savings and the feature-rich concept gives plenty of headroom to grow for both Tier 1s and OEMs.

Powering and Safeguarding AURIX™ TC4x: the TLF4x OPTIREG™ PMIC

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.
