Features
■ Fully integrated miniature module – Emitter: 940 nm invisible laser (VCSEL) and its analog driver – Low-power microcontroller running advanced digital firmware – Size: 4.4 x 2.4 x 1 mm
■ Fast, accurate distance ranging – Histogram based technology – Up to 300 cm+ detection with full field of view (FoV) – Immune to cover glass cross-talk and fingerprint smudge at long distance with patented algorithms (direct ToF) – Dynamic fingerprint smudge compensation – Short distance, high accuracy linearity – Multi target detection and distance measurement
■ Typical full FoV: 25 °
■ Easy integration – Reflowable component – Part-to-part or generic shape crosstalk calibration available – Single power supply – Works with many types of cover glass materials – I²C interface (up to 1 MHz) – Xshutdown (reset) and interrupt GPIO to optimize ranging operation – C and Linux full set of software drivers for turnkey ranging

Applications
■ Service robots and vacuum cleaners (wall following and fast obstacle detection)
■ Sanitary (robust user detection whatever the target reflectance)
■ Smart buildings and smart lighting (user detection to wake up devices)
■ IoT (user and object detection)
■ Laser assisted autofocus (AF): enhances the camera AF system speed and robustness, especially in difficult scenes (low light and low contrast); ideal companion for phase-detection autofocus (PDAF) sensors.
■ Video focus tracking assistance Time-of-Flight ranging sensor with multi target detection VL53L3CX Datasheet DS13204 - Rev 2 - February 2020 For further information contact your local STMicroelectronics sales office.
