VL53L3CX

Overview

The VL53L3CX is a Time-of-Flight (ToF) ranging sensor from STMicroelectronics featuring multi-target detection and high-performance ranging up to 310cm. It utilizes patented FlightSense technology to provide distance measurements independent of target reflectance and size. This sensor integrates a SPAD array and physical infrared filters to achieve robust performance in diverse lighting conditions.

Why Choose This Part

The VL53L3CX excels at multi-target detection, allowing the sensor to distinguish between multiple objects within the Field of View. It includes automatic smudge correction to maintain accuracy even if the optical cover glass becomes contaminated. Operating over an I2C interface, it provides a compact solution for distance sensing with a wide supply voltage range of 2.6V to 3.5V.

Applications

Getting Started

Engineers should begin with the X-NUCLEO-53L3A2 expansion board paired with an STM32 Nucleo-64 development platform. Use the STSW-IMG015 software expansion for the STM32Cube ecosystem to access drivers and example code for ranging and multi-target analysis. Ensure the optical path is clear and use the ST FlightSense API for high-level integration.
