AWR1642 and IWR1642 FMCW Radar Sensors

Texas Instruments' AWR1642 and IWR1642 are single-chip 76 GHz to 81 GHz FMCW radar sensors integrating DSP and MCU

Texas Instruments' AWR1642 and IWR1642 devices are self-contained FMCW radar sensor single-chip solutions that simplify the implementation of automotive radar (AWR1642) and mmWave sensors in the band of 76 GHz to 81 GHz. They are built on Texas Instruments’ low-power 45 nm RFCMOS process, which enables a monolithic implementation of a 2TX, 4RX system with built-in PLL and A2D converters. They integrate the DSP subsystem, which contains Texas Instruments’ high-performance C674x DSP for the radar signal processing. These devices include an Arm^® Cortex^®-R4F-based processor subsystem, which is responsible for radio (AWR1642) or front-end (IWR1642) configuration, control, and calibration. Simple programming model changes can enable a wide variety of sensor implementation with the possibility of dynamic reconfiguration for implementing a multimode sensor. Additionally, the devices are provided as complete platform solutions including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
