MCU is Optimized for Automotive 77 GHz Radar Applications

Infineon Technologies is adding a new member to its automotive microcontroller (MCU) family AURIX. TC3A will address new automotive 77 GHz radar applications such as high-end corner radar systems for advanced driver assistance systems and automated driving, says Infineon. New features include a new signal processing unit, a large SRAM memory dedicated to radar and four TriCore processors running at 300 MHz with two additional lockstep cores.

TC3A’s signal processing unit, called 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 intereference mitigation and different modulation schemes allowing first-tier customers to improve radar resolution at lower cost.

With its TC39, TC35 and TC33 AURIX devices Infineon already offers a set of MCUs for long-range, mid-range and short-range radar application. Each device has specific features enabling customers to address their different needs with performance and cost-optimized MCUs. The new TC3A will extend this portfolio at the upper performance end.

Key features of the TC3A:

  • 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
  • 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 EVITA full specification

Samples of TC3A will be available to selected customers in 2022.
