STMicroelectronics VL53L0CXV0DH/1

Overview

VL53L0CXV0DH/1 from STMicroelectronics is a miniature Time-of-Flight (ToF) laser-ranging module integrating a 940 nm VCSEL emitter, SPAD-based detection array, embedded microcontroller, and optical crosstalk compensation logic. It delivers absolute distance measurement up to 2 m with reflectance-independent accuracy in a 4.4 × 2.4 × 1.0 mm LGA12 package, enabling presence detection in access control systems and collision avoidance in robotics.

For engineers reviewing the VL53L0CXV0DH/1 datasheet, VL53L0CXV0DH/1 pinout, VL53L0CXV0DH/1 application, or VL53L0CXV0DH/1 equivalent, key selection considerations include I²C address (0x52), 2.6–3.5 V supply range, -20 to +70°C operating temperature, interrupt-capable GPIO1, and hardware standby control via XSHUT.

Technical Context

The VL53L0CXV0DH/1 implements ST's second-generation FlightSense ToF architecture using a single-photon avalanche diode (SPAD) array and proprietary timing circuitry to measure time-of-flight of invisible 940 nm laser pulses. Its embedded firmware handles full ranging sequence control-including initialization, measurement, and digital housekeeping-with on-device offset and crosstalk correction.

It supports three ranging modes (single, continuous, timed) and four configurable profiles (default, high speed, high accuracy, long range), all managed via an API-driven I²C interface. Power management includes hardware standby (XSHUT-controlled) and software standby states, with boot time ≤1.2 ms and timing budget configurable down to 8 ms per measurement.

Key Specifications

Pinout & Package

VL53L0CXV0DH/1 uses a 12-pin LGA (Land Grid Array) package with exposed thermal pad. All ground pins (GND, GND2, GND3, GND4, AVSSVCSEL) must be connected to system ground; AVDD and AVDDVCSEL are separate supply inputs requiring local 100 nF + 4.7 µF decoupling; DNC pin must remain unconnected.

FAQ

What is the maximum measurable distance and under what conditions?

The VL53L0CXV0DH/1 achieves up to 2 m absolute distance measurement in standard indoor ambient light conditions with typical white target reflectance. This range is maintained across varying surface reflectances (1% to 100%) due to on-chip histogram-based signal processing and embedded crosstalk compensation-not dependent on external calibration.

Does the device require external optical components or calibration?

No external lenses, filters, or optical alignment fixtures are needed-the module integrates a 940 nm VCSEL, SPAD array, and internal IR filter in a sealed LGA package. Factory calibration data is stored in NVM, and optional customer calibration (offset, crosstalk, temperature) can be performed once during manufacturing using the provided API.

How is low-power operation achieved in battery-powered applications?

Hardware standby mode, activated by pulling XSHUT low, reduces current draw to less than 1 µA while preserving configuration. The device wakes instantly upon XSHUT rising edge, then completes boot in ≤1.2 ms. Combined with programmable ranging timing budgets (as low as 8 ms), this enables multi-year operation on coin-cell batteries.

Can multiple VL53L0CXV0DH/1 sensors operate on the same I²C bus?

Yes-each unit supports I²C address change via software command (register 0x8A), allowing up to 127 unique addresses on one bus. Default address is 0x52. Address modification requires individual addressing during initialization, and must be done before enabling other devices on the same bus.
