Single-Chip 76-to-81GHz mmWave Sensor Integrating MCU and Hardware Accelerator　The IWR1443 device is an integrated single-chip mmWave sensor based on FMCW radar technologycapable of operation in the 76- to 81-GHz band with up to 4 GHz continuous chirp. The device is built withTI’s low-power 45-nm RFCMOS process, and this solution enables unprecedented levels of integration inan extremely small form factor. The IWR1443 is an ideal solution for low-power, self-monitored, ultraaccurateradar systems in the 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 ofmmWave sensors in the band of 76 to 81 GHz. The IWR1443 includes a monolithic implementation of a3TX, 4RX system with built-in PLL and A2D converters. The device includes fully configurable hardwareaccelerator that supports complex FFT and CFAR detection. Additionally, the device includes two ARMR4F-based processor subsystems: one processor subsystem is for master control, and additionalalgorithms; a second processor subsystem is responsible for front-end configuration, control, andcalibration. Simple programming model changes can enable a wide variety of sensor implementation with
the possibility of dynamic reconfiguration for implementing a multimode sensor. Additionally, t...
