A 3D direct ToF LiDAR module, the VL53L9CX from STMicroelectronics offers 2.3k-zone resolution for low-compute edge AI systems. This compact all-in-one module integrates a SPAD array, post-processing SoC, two VCSELs, a BCD VCSEL driver, infrared filters, metasurface optical elements (MOEs), and PMIC. It enables high-resolution spatial awareness in robotics, industrial automation, smart buildings, and healthcare.
The VL53L9CX provides 2,268 ranging zones (54×42) across a wide 55°×42° field of view, allowing detailed 3D depth mapping and precise detection of small objects, contours, and edges. With stacked BSI SPAD sensors and MOEs, the module delivers fast, accurate ranging from less than 5 cm to 8.8 m with up to 1% accuracy and frame rates up to 100 fps.
Dual-scan flood illumination reduces motion artifacts and eliminates dead zones while enhancing small-object detection. It also combines 2D infrared and 3D depth imaging, simplifying post-processing and enabling edge AI applications to run on small MCUs.
The VL53L9CX is supplied in a miniature reflowable package. Mass production is scheduled for July 2026.
