Mouser starts to stock Texas Instruments' IWR1843 sensor
Published: 27 January 2020 - Christian Lynn
Mouser Electronics confirms a new product introduction (NPI) - it now stocks the IWR1843 industrial radar sensor from Texas Instruments (TI).
Based on TI's proprietary low-power 45-nm RFCMOS process, these ultra-wideband millimetre wave (mmWave) sensors are supplied in small form factor packages, suited for deployment in space-constrained environments. This, in turn, fits them within applications such as radar hardware for building and factory automation systems, as well as traffic monitoring, materials handling and intelligent robotics, for example.
The IWR1843 radar sensor itself is a single-chip frequency-modulated continuous-wave (FMCW) device that supports 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.
