TI industrial radar sensor in stock at Mouser

The IWR1843 industrial radar sensor from Texas Instruments (TI) is in stock at Mouser Electronics. Based on TI's proprietary low-power 45-nm RFCMOS process, these ultra-wideband millimetre wave (mmWave) sensors enable exceptional levels of integration. They are supplied in extremely small form factor packages, which make them highly suitable for deployment in space-constrained environments.

Among the target applications for these devices are the low-power, self-monitored, ultra-accurate radar hardware used in building and factory automation systems, as well as for traffic monitoring, materials handling, people detection/counting and intelligent robotics.

The IWR1843 radar sensors are single-chip frequency-modulated continuous-wave (FMCW) devices that support operation in the 76-GHz to 81-GHz mmWave spectrum.

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

The sensors have digital signal processor (DSP) subsystems embedded into them for radar signal processing purposes.

These are based on TI's high-performance C674x DSP cores.

In addition, built-in self-test (BIST) processor subsystems take responsibility for radio configuration, control and calibration activities.

Each sensor also has an on-board user-programmable Arm Cortex-R4F processor for undertaking object tracking/classification, AUTOSAR and interface control.

Mouser also stocks the TI IWR1843 BoosterPack – an easy-to-use evaluation board with direct connectivity to TI’s popular LaunchPad development platform.

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