TC3A - Automotive Microcontroller for Radar Systems in Driver Assistance Applications

Infineon Technologies announced a new member TC3A to its automotive microcontroller family AURIX that can address automotive 77GHz radar applications such as high-end corner radar systems for advanced driver assistance systems and automated driving. TC3A has a new signal processing unit, the SPU 2.0 is an evolution of Infineon’s accelerator for radar processing with reduced latencies for Fast Fourier Transform (FFT) processing, extended capability for interference mitigation and different modulation schemes allowing first-tier customers to improve radar resolution at lower cost.

 

Features of TC3A Microcontroller:

  • Four cores with TriCore architecture with two lockstep cores running at 300 MHz providing safe processing capability
  • SPU 2.0 with extended features for realtime interference mitigation and lower resources consumption
  • A large 6 MB of embedded SRAM to store data during processing
  • High-speed radar MMIC (Monolithic Microwave Integrated Circuit) interface with up to 600 Mbps
  • Hardware Security Module (HSM) compliant with the EVITA full specification

 

With its TC39, TC35 and TC33 AURIX devices Infineon provides a set of microcontrollers for long-range, mid-range and Short range radar applications. Each of this device has different specifications that can help the customers to address their different needs with performance and cost optimized microcontrollers. The new TC3A will extend this portfolio to evolve into automated driving, enabling Infineon to work with start-ups, industry leaders, and tech giants to accelerate innovations for radar systems. The samples of TC3A will be available for selected customers in 2022.
