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
