3 Description

Texas Instruments introduces the IWRL6432WMOD, the radar module presenting a significant advancement in

low-power industrial radar technology. This compact 31mm × 15mm module integrates a 60GHz patch antenna,

on-board power management, flash memory, passives and crystal, eliminating the need for specialized mmWave

system design expertise while providing simple software configuration options for range, sensitivity, and regions

of interest. The module is distinguished by its comprehensive targeted certification with FCC, RED, TELEC that

eliminates cost and effort for certification at the end product. Additionally the module provides either SPI based

point cloud data outputs or GPIO based presence indication which aids flexible implementation. By addressing

customer readiness challenges and enabling autonomous operation across applications such as motion sensing,

occupancy detection, and smart home devices, this TI-designed, supported, and distributed device significantly

reduces development complexity and accelerates time-to-market for customers seeking to embed mmWave

radar sensor capabilities in their products.
