Texas Instruments IWRL6432 Industrial mmWave Radar Sensors

Texas Instruments IWRL6432 Industrial mmWave Radar Sensors are integrated single-chip mmWave sensors based on FMCW radar technology. These sensors operate at 57GHz to 63.9GHz band with 7GHz continuous bandwidth and are divided into four power domains. These radar sensors support multiple low-power modes, such as idle and deep sleep modes. The IWRL6432 sensors are divided into four power domains, such as RF/Analog sub-systems, Front-End Controller Sub-System (FECSS), Application Sub-System (APPSS), and Hardware Accelerator (HWA). Typical applications include building/factory automation, commercial/residential security, personal electronics, presence/motion detection, and gesture detection/recognition for human-machine interfaces.
