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 in any specific area.

Features

·Suited for 1D to 3D sensing

     -  1 Tx and 2x2 Rx antennas detect azimuth/elevation angle, velocity and distance

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

    -  -Sensing area :

        Up to 0.5m*1 with a resolution of less than 1cm*2　(in case of palm gesture)

        Up to 15m*1 with a resolution of less than 12.4cm*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 (4.0mm x 7.0mm, 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

        *2: To be changed according to further study
