ULP RF ranging sensors for automotives to detect passenger movement

Socionext introduced the SC1260 Series radio-frequency ranging sensors for automotive applications. This new series utilizes the 60GHz frequency band and time-division multiplexing (TDM-MIMO) operation with multiple transmitting and receiving antennas that can detect the position and movement of passengers in a vehicle with maximum accuracy. This SC1260 has an all-in-one configuration that incorporates antennas and radar signal operation circuits, to achieve maximum detection accuracy in an ultra-low-power, ultra-compact package.
The high-precision sensors use a wide band of 6.8GHz (57.1 to 63.9GHz) with an expanded number of receiving antennas by TDM-MIMO operation and built-in radar signal operation circuits for range-finding and angle calculation. The devices enable easy acquisition of three-dimensional (3D) position information without requiring advanced expertise in high-frequency devices and signal operation. Combines antennas, RF circuits, AD converters, FIFO memory, SPI interface, and intelligent power control sequencer for flexible duty cycle control. Power required is only 0.72mW at 0.1% duty cycle operation. These capabilities make the series optimal for applications such as tracking the position and movements of passengers in a vehicle while suppressing the load on the ve...
