New SC1260 Series Detects Position, Movement of Vehicle Passengers with Maximum Accuracy

YOKOHAMA, Japan and MILPITAS, Calif., May 30, 2023 /PRNewswire/ -- Socionext Inc., a global leader in high precision sensor technology, today 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 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 frequency wireless communication ICS and 24GHz radio-frequency ranging sensors, Socionext has become the first company worldwide to develop ultra-compact, ultra-low power 60GHz radio-frequency ranging sensors for automotive applications with built-in radar signal operation circuits for range-finding and angle calculations," said Teruaki Hasegawa, Head of Socionext's IoT & Radar Sensing Business Unit.

Moreover, TDM-MIMO operation 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-frequency ranging sensor devices and will serve the diverse needs of a variety of customers in this field by bringing new and enhanced user experiences.
