Automotive radar sensors offer outstanding levels of integration

Update: April 14, 2023

Mouser now stocks the AWR1843AOP automotive radar sensor from Texas Instruments. The sensor offers engineers excellent levels of integration in an exceptionally small form factor for low-power, self-monitored, ultra-accurate automotive radar systems.

The sensor is an Antenna-On-Package (AOP) device for operations in the 76GHz to 81GHz band. Built with the company’s low-power 45nm RFCMOS process, it combines a DSP subsystem, integrating high-performance C674x DSP for radar signal processing, with a BIST processor subsystem, responsible for radio configuration, calibration and control, with a user-programmable Arm Cortex-R4F processor for automotive interfacing.

The sensor’s hardware accelerator block (HWA) can achieve radar processing and offloads of the DSP to execute higher-level algorithms. Simple programming model changes allow various sensor applications, such as door opening, parking, blind spot, and lane change applications, with dynamic reconfiguration for implementing a multimode sensor. Further, the device is offered as a complete platform solution, including reference hardware design, software drivers, sample configurations, API guide, and user documentation.

The company’s AWR1843AOPEVM evaluation module supports the sensor. The module is a simple-to-use platform for evaluating the AWR1843AOP radar sensor. It allows direct connectivity to the MMWAVEICBOOST and DCA1000EVM development kits (sold separately), allowing designers to create software for the on-chip C67x DSP core and low-power Arm Cortex-R4F processors.
