VL53L0X World’s smallest Time-of-Flight ranging and gesture detection sensor Datasheet - production data Applications • User detection for personal computers/ laptops/tablets and IoT (energy saving) • Robotics (obstacle detection) • White goods (hand detection in automatic faucets, soap dispensers etc.) • 1D gesture recognition. • Laser assisted autofocus. Enhances and speeds up camera autofocus system performance, especially in difficult scenes (low light levels, low contrast) or fast moving video mode. reflectances unlike in laser-ranging module housed Description The VL53L0X is a new generation Time-of-Flight (ToF) the smallest package on the market today, providing accurate distance measurement whatever the target conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, opening the door to various new applications. The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology. The VL53L0X’s 940 nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distances, higher immunity to ambient light, and better robustness to cover glass optical crosstalk. Features • Fully integrated miniature module – 940 nm laser VCSEL – VCSEL driver – Ranging sensor with advanced embedded micro controller – 4.4 x 2.4 x 1.0 mm • Fast, accurate distance ranging – Measures absolute range up to 2 m – Reported range is independent of the target reflectance – Advanced embedded optical cross-talk compensation to simplify cover glass selection • Eye safe – Class 1 laser device compliant with latest standard IEC 60825-1:2014 - 3rd edition • Easy integration – Single reflowable component – No additional optics – Single power supply – I2C interface for device control and data transfer – Xshutdown (reset) and interrupt GPIO – Programmable I2C address April 2018 This is information on a product in full production.

Overview 1.4 Application schematic Figure 3 shows the application schematic of the VL53L0X. Figure 3. VL53L0X schematic VL53L0X Note: Note: Note: Note: Note: Capacitors on external supply AVDD should be placed as close as possible to the AVDDVCSEL and AVSSVCSEL module pins. External pull-up resistors values can be found in I2C-bus specification. Pull-up are typically fitted only once per bus, near the host. Recommended values for pull-up resistors for an AVDD of 2.8V and 400KHz I2C clock would be 1.5k to 2k Ohms. XSHUT pin must always be driven to avoid leakage current. Pull-up is needed if the host state is not known. XSHUT is needed to use HW standby mode (no I2C comm). XSHUT and GPIO1 pull up recommended values are 10k Ohms GPIO1 to be left unconnected if not used 8/40 DocID029104 Rev 2
