The AWR1843 device is an integrated single-chip FMCW radar sensor
capable of operation in the 76- to 81-GHz band. The device is built with TI’s low-power 45-nm
RFCMOS process and enables unprecedented levels of integration in an extremely small form factor.
The AWR1843 is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the
The AWR1843 device is a self-contained FMCW radar sensor single-chip
solution that simplifies the implementation of Automotive Radar sensors in the band of 76 to 81
GHz. It is built on TI’s low-power 45-nm RFCMOS process, which enables a monolithic implementation
of a 3TX, 4RX system with built-in PLL and A2D converters. It integrates the DSP subsystem, which
contains TIs high-performance C674x DSP for the Radar Signal processing. The device includes a
BIST processor subsystem, which is responsible for radio configuration, control, and calibration.
Additionally the device includes a user programmable ARM R4F based for automotive interfacing. The
Hardware Accelerator block (HWA) can perform radar processing and can help save MIPS on the DSP for
higher level algorithms. Simple programming model changes can enable a wide variety of sensor
implementation (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing
a multimode sensor. Additionally, the device is provided as a complete platform solution including
TI reference designs, software drivers, sample configurations, API guides, and user
