Mouser adds TI’s latest mmWave sensors

By eeNews Europe

The sensor is based on TI’s proprietary low-power 45-nm RFCMOS process. The ultra-wideband millimetre wave (mmWave) sensors come in small packages for use in space-constrained environments.

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. TI’s RFCMOS process allows monolithic implementation of a system with three transmit and four receive channels, as well as built-in phase lock loop (PLL) and ADCs. Embedded DSP subsystems allow radar signal processing. The DSPs are based on TI’s C674x DSP cores. Each processor subsystem has built-in self-test and is in charge of radio configuration, control and calibration activities. The sensors also feature an on-board user-programmable Arm Cortex-R4F processor for undertaking object tracking/classification, AUTOSAR and interface control.

Mouser will also stock the TI IWR1843 BoosterPack evaluation board that can connect to TI’s LaunchPad development platform. The BoosterPack provides everything needed to develop software for the on-chip C67x DSP core and low-power Arm Cortex-R4F controller, including on-board emulation for programming and debugging, and buttons and LEDs for quick integration of a simple user interface.
