Datasheet

The AWR1843 automotive radar sensor from Texas Instruments (TI) is in stock at Mouser Electronics. Built with TI’s low-power 45-nm RFCMOS process, the AEC-Q100 qualified AWR1843 ultra-wideband millimeter wave (mmWave) sensor enables exceptional levels of integration in an extremely small form factor in low-power, self-monitored, ultra-accurate radar systems in the automotive space.

The AWR1843 is an integrated single-chip frequency-modulated continuous-wave (FMCW) radar sensor capable of operation in the 76- to 81-GHz millimeter wave spectrum.

TI’s RFCMOS process enables a monolithic implementation of a system with three transmit (TX) and four receive (RX) channels plus built-in phase lock loop (PLL) and analog-to-digital converters (ADCs).

The sensor integrates a digital signal processor (DSP) subsystem, based on TI’s high-performance C674x DSP, for radar signal processing, as well as a built-in self-test (BIST) processor subsystem responsible for radio configuration, control, and calibration.

An onboard user-programmable ArmCortex-R4F processor enables object tracking and classification, AUTOSAR, and interface control.

Mouser also stocks the TI AWR1843 BoosterPack, an easy-to-use evaluation board with direct connectivity to TI’s LaunchPad development kits.

The BoosterPack contains everything required to start developing software for the on-chip C67x DSP core and low-power Arm Cortex-R4F controller, including onboard emulation for programming and debugging as well as buttons and LEDs for quick integration of a simple user interface.
