Overview

The IWR6843ABGABL is an integrated single-chip mmWave sensor based on FMCW radar technology operating in the 60GHz to 64GHz band. It combines a high-performance RF front-end with an Arm Cortex-R4F MCU and a C674x DSP to enable on-chip beamforming and advanced signal processing for industrial automation.

Why Choose This Part

This SoC features a dedicated C674x DSP and a hardware accelerator for FFT and CFAR processing, significantly reducing the computational load on the main ARM core. It supports functional safety requirements through built-in self-test (BIST) and monitoring of the RF front-end and digital subsystems.

Applications

Industrial Robotics
Utilizes 60GHz radar for area monitoring, collision avoidance, and safety guarding in automated factory environments.
Building Automation
High-resolution occupancy detection, people counting, and motion tracking for HVAC and lighting control systems.
Level Sensing
Precise non-contact measurement of liquid or solid levels in tanks and silos using high-frequency radar chirps.
Functional Safety Systems
Integrated into SIL-rated environments for presence detection where high reliability and self-testing are required.
