Texas Instruments' IWR1443 integrated single-chip mmWave sensor is based on frequency-modulated continuous wave (FMCW) radar technology and is designed for operation in the 76 GHz to 81 GHz band with up to 4 GHz continuous chirp. It is built with TI’s low-power 45 nm radio frequency complementary metal-oxide semiconductor (RFCMOS) process enabling unprecedented levels of integration in an extremely small form factor. The IWR1443 is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in industrial applications such as building automation, factory automation, drones, material handling, traffic monitoring, and surveillance.
The IWR1443 device is a self-contained, single-chip solution that simplifies the implementation of mmWave sensors in the band of 76 GHz to 81 GHz. It includes a monolithic implementation of a 3TX, 4RX system with built-in phase-locked loop (PLL) and analog-to-digital converters (ADCs). This device includes fully configurable hardware accelerator that supports complex fast Fourier transform (FFT) and constant false alarm rate (CFAR) detection.
The IWR1443 includes two Arm® R4F-based processor subsystems including one processor subsystem for master control and additional algorithms. The second processor subsystem is responsible for front-end configuration, control, and calibration. A wide variety of sensor implementation with the possibility of dynamic reconfiguration for implementing a multimode sensor is enabled by simple programming model changes. This device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, application program interface (API) guide, training, and user documentation.
