Single-chip mmWave sensors from TI in mass production

May 31, 2018 // By Rich Pell
Texas Instruments (Dallas, TX) has announced the mass production of its ultra-wideband AWR1642 and IWR1642 millimeter-wave (mmWave) sensors.

This marks the industry's "first and only" single-chip, CMOS millimeter-wave sensor in mass production, says the company. The chips are used in automotive and industrial applications, respectively, including for vehicle occupancy detection, people counting in buildings, machine and human interaction, and more.

The sensors support frequencies from 76 to 81 GHz and, says the company, deliver three times more accurate sensing and the smallest footprint at a fraction of the power of competing sensor technologies. They are expected to first appear in vehicles on the road in late 2018, to enable new advanced driver assistance systems (ADAS) applications.

In addition, says the company, engineers are using the automotive-qualified AWR1642 sensor for free space and obstacle detection near doors and trunks, occupancy detection inside the cabin, intruder alert, and smarter automated parking. A Vehicle Occupant Detection Reference Design is available offering a system-level overview and software examples for using the AWR1642 sensor to detect people inside a vehicle.

The IWR1642 sensor is offered as an ideal solution for low-power, self-monitored, ultra-accurate radar systems in applications such as building automation, factory automation, drones, material handling, traffic monitoring, and surveillance. A People Counting and Tracking Reference Design demonstrates how the chip can be used for indoor and outdoor people counting applications. A Traffic Monitoring Object Detection and Tracking Reference Design demonstrates how the technology can be used for robust, long-range sensing in traffic monitoring and other applications.
