The AWR6843AOP is an Antenna-on-Package (AOP) device that is an evolution within the single-chip radar device family from Texas Instruments (TI). This device enables unprecedented levels of integration in an extremely small form factor and is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the Automtive space.Multiple automotive qualified variants are currently available including Functional Safety-Compliant devices (ASIL-B) and non-functional safety devices.

It integrates a DSP subsystem, which contains TI’s high-performance C674x DSP for the Radar Signal processing. The device includes a BIST processor subsystem, which is responsible for radio configuration, control, and calibration. Additionally, the device includes a user programmable Arm Cortex-R4F based for automotive interfacing. The Hardware Accelerator block (HWA) can perform radar processing and can offload the DSP in order to execute higher level algorithms. Simple programming model changes can enable a wide variety of sensor applications with the possibility of dynamic reconfiguration for implementing a multimode sensor. Additionally, the device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
