2.3.1 AWRL1432 Single-Chip Radar Solution

TI's AWRL1432 is an integrated single-chip low-power 77GHz mmWave sensor based on FMCW radar technology, capable of operation in the 76GHz to 81GHz band. The device is partitioned into four main power domains with separate controls for each state based on use case requirements:

  • RF/analog subsystem
  • Front-end controller subsystem (FECSS)
  • Application subsystem (APPSS)
  • Hardware accelerator (HWA)

Additionally, the AWRL1432 is built with TI’s low-power 45nm RF CMOS process and enables unprecedented levels of integration in an extremely small form factor. The device has two transmitters and three receivers with a fractional-N phase-locked loop for precise and linear chirp synthesis. Based on real-only baseband architecture, the device supports an IF bandwidth of 5MHz. The presence of Arm® M4F® core, TI Radar Hardware Accelerator (HWA 1.2), and 1MB of on-chip RAM enables custom algorithm development.
