VL53L1CXV0DH in ST VL53Lx Time-of-Flight Family
The VL53L1CXV0DH family by STMicroelectronics represents a significant evolution in Time-of-Flight (ToF) sensing, utilizing the FlightSense technology to provide accurate distance measurement regardless of target reflectance. Operating via an I2C interface, this sub-family integrates a SPAD receiving array, a 940 nm Class 1 laser emitter, and physical infrared filters to achieve superior ranging performance up to 4 meters. It is designed for applications requiring precise proximity detection, long-distance sensing, and multi-target detection within a compact optical package.
Variants within the VL53L1CXV0DH sub-family primarily differ in their packaging options and specific calibration profiles tailored for different cover window materials. While the core silicon remains the same, some versions are optimized for high-volume consumer integration with specific tape-and-reel specifications or include minor firmware adjustments to improve multi-zone ranging performance or power consumption profiles during long-term continuous sensing operations.
