Automotive 60GHz Radio-wave sensor
for In-Cabin Sensing SC1260AR3

SC1260AR3 is an extremely low-power, small size and intelligent
all-in-one CMOS 60GHz radar sensor device with AiP(Antenna inPackage), available for 3D (including 1D, 2D) sensing, andsuitable for in-cabin sensing application.
It contains a high-performance radar signal processing unit anddetects the 3D position of moving objects and the presence of theobjects in any specific area.
SC1260AR3

 Features● High resolution 1D to 3D sensing- 2-Tx and 4-Rx integrated antennas supporting TDM-MIMO operation realize 6x2 virtual antenna array- Wide bandwidth (6.8GHz max.) and high-accuracy linear chirp FMCW radar- Example of sensing target: infant lying in the child safety seat or persons sitting on the seat

● Highly integrated device enabling easy hardware design- Integrate radar signal processing unit (Distance/Angle/Presence detection), antennas, RF circuit, ADC,FIFO and SPI interface- Enable to use reasonable PCB, less BOM and easy assembly- Smallest package for all-in-one interior radio sensor (6.0mm x 9.0mm, BGA package)● Low power consumption reducing battery load
- 4-level operation states (Shutdown, Deep Sleep, Light Sleep, Sensing)- Intelligent power control sequencer managing flexible duty cycle operation realize <1mW averaging
power consumption- Activate other device by integrated presence detection functionality
