60 GHz radar sensors and MCUs target in-cabin monitoring
Enabling ultra-short range automotive applications, this sensor-MCU combination is ideal for in-cabin monitoring systems (ICMS) sub-systems.

With XENSIV™ BGT60ATR24C AEC-Q100 radar sensors, AURIX™ microcontrollers and OPTIREG™ PMICs, Infineon Technologies AG offers a wide variety of products for an ultra-wideband, ultra-low power and cost-performance scalable architecture for in-cabin monitoring systems (ICMS) sub-systems. The devices support the use of new signal processing techniques enabling robustness and a good compromise between computational costs, the degree of information as well as the power consumption of the system.

ICMS are reshaping the concept of passenger safety in cars. Various applications such as left-behind child detection, driver well-being or occupancy sensing increase road safety and the protection in vehicles. Radar in particular is a promising technology to address these applications due to its ability to detect micro-motions and vital signs.

The XENSIV BGT60ATR24C radar sensor is a cognitive sensing device with multiple transmit/receive for virtual array configurations, a highly agile modulation generation mechanism, automatic power mode configurability as well as simplified interfaces between RF and the processing side. Furthermore, the AURIX TC3xx MCU family combines performance with a powerful safety architecture. The family integrates a fast radar signal processing unit and enhanced security with the second-generation of the hardware security module (HSM). This includes asymmetric cryptography accelerators and full EVITA support.

This sensor-MCU combination makes the 60 GHz automotive portfolio ideal for ICMS applications. In addition, the partnerships with bitsensing, a South Korean imaging radar technology start-up, and Caaresys, a start-up based in Israel, enables customers to accelerate their development cycle.
