Automotive sensor ideal for low-power and ultra-accurate radar systems

21-11-2019 | Texas Instruments | Test & Measurement

Texas Instruments AWR1843 mmWave Automotive Radar Sensor employs the low-power 45nm RFCMOS process and facilitates unprecedented levels of integration in a remarkably small form factor. The device can operate in the 76GHz to 81GHz band, which makes it an excellent solution for self-monitored, low-power, ultra-accurate radar systems in the automotive space.


The company's RFCMOS process provides a monolithic implementation of a 3TX, 4RX system with built-in PLL and A2D converters. This feature combines the DSP subsystem, which includes the company’s high-performance C674x DSP for Radar Signal processing. The sensor includes a BIST processor subsystem, which is responsible for radio configuration, control, and calibration.


Furthermore, the sensor comprises a user-programmable ARM R4F base for automotive interfacing. The HWA performs radar processing and adds to saving MIPS on the DSP for higher-level algorithms. Simple programming model changes can help a wide assortment of sensor implementation (Short, Mid, Long) with the opportunity of dynamic reconfiguration for implementing a multimode sensor.


The device is presented as a complete platform solution, including TI reference designs, software drivers, sample configurations, API guides, and user documentation. The AWR1843-Q1 variant is AEC-Q100 qualified for automotive applications.
