60GHz Radio-wave ranging sensor
3D Detection model SC1240AR3

SC1240AR3 is an extremely low-power and intelligent CMOS 60GHz
radar sensor device and available for 3D (including 1D, 2D) sensing
without an external MCU.
It contains a high-performance signal processing unit and detects
the 3D position of moving objects and the presence of the objects inany specific area.

 Features● Suited for 1D to 3D sensing- 1 Tx and 2x2 Rx antennas detect azimuth/elevation angle,velocity and distance

SC1240AR3- Wide bandwidth (6.8 GHz max.) and high-accuracy linear chirp FMCW radar- Sensing area:

Up to 0.5 m*1 with a resolution of less than 1 cm*2(in case of palm gesture)
Up to 15 m*1 with a resolution of less than 12.4 cm*2 (in case of human detection)● Highly integrated device enabling easy hardware design- Integrates signal processing unit (Distance/Angle/Presence detection), antennas, RF circuit, ADC,FIFO and SPI interface, and has a self-boot function- Enable to use reasonable PCB, less BOM and easy assembly- Small package (4.0 mm x 7.0 mm, BGA package)● Low power consumption- 4-level operation states (Shutdown, Deep Sleep, Light Sleep, Sensing)- Intelligent power control sequencer managing flexible duty cycle operation*1: Depending on sensor configuration and environmental conditions
