Infineon Technologies AG will add a new member to its automotive microcontroller family AURIX to address new automotive 77 GHz radar applications such as high-end corner radar systems for advanced driver assistance systems and automated driving. 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.
SPU 2.0 signal processing unit 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 a lower cost.
Infineon AURIX TC39, TC35, and TC33 devices offer long-range, mid-range and short-range radar applications. Each device has specific features enabling customers to address different needs with performance and cost-optimized microcontrollers. The new TC3A extends 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.
