Single-chip 76-GHz to 81-GHz automotive radar sensor integrating MCU and hardware accelerator

The

AWR1443 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 with an integrated ARM R4F processor and a hardware accelerator for radar

data processing, and this solution enables unprecedented levels of integration in an

extremely small form factor. AWR1443 is an ideal solution for low-power,

self-monitored, ultra-accurate radar systems in the automotive space.

The

AWR1443 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 enables a monolithic implementation of a 3TX, 4RX system with built-in PLL

and ADC converters. 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 documentation.

The

requirements for a radar device, in terms of radar data cube memory, processing

capacity, and functional safety monitoring, vary for different applications. In this

context, the AWR1443 can be viewed as a 77-GHz radar-on-a-chip solution for

entry-level radar applications
