TI AWR1843ARBGALPRQ1

The AWR1843AOP is an antenna-on-package device capable of operating in the 76GHz to 81GHz band. The device is built using TI's low-power 45nm RFCMOS process and achieves excellent integration in an ultra-compact package. The AWR1843AOP is an ideal solution for low-power, self-monitoring, ultra-precise radar systems in automotive applications. It integrates a DSP subsystem containing TI's high-performance C674x DSP for radar signal processing. The device includes a BIST processor subsystem responsible for radio configuration, control, and calibration. Additionally, the device incorporates a user-programmable Arm Cortex-R4F for automotive connectivity. The Hardware Accelerator (HWA) block performs radar processing and offloads the DSP, enabling execution of more advanced algorithms. Simple programming model changes support a wide variety of sensor applications, with dynamic reconfiguration capability enabling multi-mode sensing. Furthermore, the device is offered as a complete platform solution that includes hardware reference designs, software drivers, sample configurations, API guides, and user documentation.
