VL53L1CXV0FY/1 ToF Ranging Sensor | FlightSense Laser Distance Sensor | STMicroelectronics

VL53L1CXV0FY/1

Third-generation FlightSense™ ToF laser-ranging sensor integrating a 940 nm emitter and SPAD array, enabling distance measurement up to around 4 m, programmable field of view and multizone ranging, with an I²C interface for easy MCU connectivity in smart home, robotics, and human-interaction detection.

Product Description

Product Overview

The VL53L1CXV0FY/1 is a member of STMicroelectronics’ VL53L1 ToF family. Using direct ToF technology, it measures absolute distance by timing the round-trip of light pulses, largely independent of target color or reflectance.

It combines a 940 nm Class 1 laser emitter, a SPAD array, IR filters, optics, and an on-chip MCU running ranging firmware to achieve robust performance under varying ambient light and with different cover window materials.

The VL53L1 family typically supports up to ~4 m ranging and up to 50 Hz update rate; some distributors list VL53L1CXV0FY/1 as “0–62 cm” range, reflecting a specific application profile rather than the intrinsic silicon limit.

Packaged in a miniature reflowable module (around 4.9 × 2.5 × 1.56 mm) powered from a single 2.8 V supply and using an I²C interface, it fits space-constrained designs in end products.
