Socionext Introduces Ultra-compact, Ultra-low-power 60GHz Radio-wave Ranging Sensors for Automotive Applications

31 May 2023

Socionext Inc., a global leader in high-precision sensor technology, today introduced the SC1260 Series radio-wave ranging sensors for automotive applications. This new series utilizes the 60GHz frequency band and time-division multiplexing (TDM-MIMO) processing 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 incorporating antennas and radar signal processing 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 processing and built-in radar signal processing 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 processing. combines antennas, wireless circuits, AD converters, FIFO memory, SPI interface, and intelligent power control sequencer for flexible duty cycle control. The 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 vehicle battery when the engine is off.

The SC1260 Series complies with the global broadband 60GHz radio equipment standard. Sample and evaluation kit shipments are scheduled for June, with production volumes to be available in Q1 2024.

“By leveraging our extensive experience and knowledge accumulated through the development of millimeter-wave wireless communication ICS and 24GHz radio-wave ranging sensors, Socionext has become the first company worldwide to develop ultra-compact, ultra-low power 60GHz radio-wave ranging sensors for automotive applications with built-in radar signal processing circuits for range-finding and angle calculations in automotive applications,” said Teruaki Hasegawa, Head of Socionext's IoT & Radar Sensor Business Unit.

Moreover, TDM-MIMO processing enables high-precision sensing, such as the detection of passengers when three people are sitting in a row inside the vehicle.

Following the debut of its SC1260AR3, Socionext will continue to develop products that meet customer needs and applications.

Socionext is a leader in the advancement of sensing applications through its unique lineup of radio-wave ranging sensor devices and will continue to be a world leader in this field by championing new product development for enhancing user experience.
