The AWRL1432 mmWave Sensor device is an integrated single chip mmWave sensor based on FMCW radar technology. The device is capable of operation in the 76GHz to 81GHz band and is partitioned into mainly four power domains:

  • RF/Analog Sub-System: This block includes all the RF and Analog components required to transmit and receive the RF signals.
  • Front-End Controller sub-System (FECSS): FECSS contains processor, responsible for radar front-end configuration, control, and calibration.
  • Application Sub-System (APPSS): APPSS is where the device implements a user programmable ARM Cortex M4 allowing for custom control and automotive interface applications. Top Sub-System (TOPSS) is part of the APPSS power domain and contains the clocking and power management sub-blocks.
  • Hardware Accelerator (HWA): HWA block supplements the APPSS by offloading common radar processing such as FFT, Constant False Alarm rate (CFAR), scaling, and compression.

AWRL1432 is specifically designed to have separate controls for each of the above-mentioned power domains to control their states (power ON or OFF) based on use case requirements. The device also features the capability to exercise various low-power states like sleep and deep sleep, where low-power sleep mode is achieved by clock gating and by turning off the internal IP blocks of the device. The device also provides the option of keeping some contents of the device, like Application image or RF profile retained in such scenarios.

Additionally, the device is built with TI’s low power 45nm RF CMOS process and enables unprecedented levels of integration in an extremely small form factor. AWRL1432 is designed for low power, self-monitored, ultra-accurate radar systems in the automotive space for applications like blind spot detection, kick-to-open, parking assist, and door obstacle detection.
