3 Description
The IWR1843AOP device is an integrated single-chip mmWave sensor based on FMCW radar technology
capable of operating in the 76- to 81-GHz band with up to 4-GHz continuous chirp. The device is built
with the low-power 45-nm RFCMOS process from Texas Instruments. This solution enables unprecedented
levels of integration in an extremely small form factor. The IWR1843AOP 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 IWR1843AOP device is a self-contained, single-chip solution that simplifies the implementation of mmWave
sensors in the band of 76 to 81 GHz. The IWR1843AOP includes a monolithic implementation of a 3TX, 4RX
system with built-in PLL, and ADC converters. The IWR1843AOP also integrates a DSP subsystem, which
contains a TI high-performance C674x DSP for the radar signal processing. The device includes an ARM R4Fbased
processor subsystem, which is responsible for front-end configuration, control, and calibration. Simple
programming model changes can enable a wide variety of sensor implementation with the possibility of dynamic
reconfiguration for implementing a multimode sensor. The Hardware Accelerator block (HWA) can perform radar
processing and can help save MIPS on the DSP for higher-level algorithms. Additionally, the device is provided
as a complete platform solution including TI reference designs, software drivers, sample configurations, API
guides, training, and user documentation.
