Socionext has recently released the SC1260 Series radio-frequency ranging sensors that are specifically designed for automotive applications.
The sensors operate on the 60GHz frequency band and utilize time-division multiplexing (TDM-MIMO) operation with multiple transmitting and receiving antennas to detect passengers' position and movement in a vehicle with maximum accuracy.
The SC1260 series boasts an all-in-one configuration that includes antennas and radar signal operation circuits, resulting in an ultra-low-power and ultra-compact package. These high-precision sensors employ a wide band of 6.8GHz (57.1 to 63.9GHz) with an increased number of receiving antennas by TDM-MIMO operation and built-in radar signal operation circuits for range-finding and angle calculation.
With this technology, acquisition of three-dimensional (3D) position information is made easy, even without advanced expertise in high-frequency devices and signal operation. Additionally, the series combines antennas, RF circuits, AD converters, FIFO memory, SPI interface, and intelligent power control sequencer for flexible duty cycle control. At 0.1% duty cycle operation, power required is only 0.72mW, making it optimal for tracking passenger positions and movements while minimizing the load on the vehicle battery when the engine is off. The SC1260 Series is compliant with the global broadband 60GHz radio equipment standard. Sample and evaluation kit shipments are scheduled for June, with production volumes available in Q1 2024.
