In stock at distributor Mouser Electronics is the AWR1843AOP automotive radar sensor from Texas Instruments.

The AWR1843AOP provides engineers with exceptional levels of integration in an extremely small form factor, for low-power, self-monitored, ultra-accurate radar systems in the automotive sector.

This sensor is an Antenna-On-Package (AOP) device for operations in the 76- to 81GHz band.

Built with Texas Instruments low-power 45-nm RFCMOS process, the AWR1843AOP integrates a DSP subsystem, combining high-performance C674x DSP for radar signal processing, with a BIST processor subsystem, responsible for radio configuration, control, and calibration, with a user-programmable Arm Cortex-R4F processor for automotive interfacing.

The AWR1843AOP's hardware accelerator block (HWA) can perform radar processing and offloads of the DSP to execute higher level algorithms.

Simple programming model changes enable a wide variety of sensor applications like door opening, parking, blind spot, and lane change applications, with 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.

The AWR1843AOP is supported by the TI AWR1843AOPEVM evaluation module, also available at Mouser Electronics.

This is an easy-to-use platform for evaluating the AWR1843AOP radar sensor and allows direct connectivity to the TI MMWAVEICBOOST and DCA1000EVM development kits (sold separately), enabling designers to develop software for the on-chip C67x DSP core and low-power Arm Cortex-R4F processors.
