Product details
Overview
VL53L1CBV0FY/1 from STMicroelectronics is a direct Time-of-Flight (dToF) laser-ranging sensor module integrating a 940 nm VCSEL emitter, SPAD-based receiving array with integrated lens, low-power microcontroller, and patented ranging firmware. It delivers up to 800 cm single-object distance measurement, 60 Hz multizone scanning (2×2 to 4×4 ROI), and multiobject detection within its field of view - enabling laser-assisted autofocus in smartphone cameras under low-light conditions.
For engineers reviewing the VL53L1CBV0FY/1 datasheet, VL53L1CBV0FY/1 pinout, VL53L1CBV0FY/1 application, or VL53L1CBV0FY/1 equivalent, key selection considerations include I²C address (0x52), 2.6–3.5 V supply range, Class 1 eye safety compliance, hardware standby via XSHUT, and interrupt-driven handshake management using GPIO1 for synchronized multizone readouts.
Technical Context
The VL53L1CBV0FY/1 implements a fully self-contained dToF system-on-module architecture: the on-chip microcontroller executes advanced temporal filtering firmware to distinguish cover-glass crosstalk from true object returns beyond 80 cm, enabling robust ranging through smudged or thick optical windows. Its SPAD array supports configurable region-of-interest (ROI) selection and histogram-based depth processing at 60 Hz.
It operates in four preset modes - ranging, multizone scanning, lite ranging, and autonomous - each managed via a turnkey C API driver. Ranging mode provides best-in-class 300+ cm accuracy with cover glass; multizone scanning outputs per-zone distance, signal rate, and quality level; autonomous mode triggers interrupts based on user-defined distance/signal thresholds without host polling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Ranging Distance | 800 cm in single-object ranging mode - enables long-range presence detection and white-goods proximity sensing. |
| Ranging Frame Rate | 60 Hz in multizone scanning mode - supports real-time video focus tracking and dynamic scene understanding. |
| I²C Interface Speed | Up to 1 MHz (Fast Mode Plus) - allows high-throughput configuration and data retrieval without bus contention. |
| Supply Voltage Range | 2.6 V to 3.5 V - compatible with standard 2.8 V LDO rails and simplifies power design in mobile/embedded systems. |
| Operating Temperature | −20 °C to +85 °C - qualified for industrial and consumer end equipment including notebooks, tablets, and smart appliances. |
| Laser Safety Class | IEC 60825-1:2014 Class 1 - no external safety measures required; safe for unattended human-proximity applications. |
| Package Dimensions | 4.4 mm × 2.5 mm × 1.56 mm LGA12 - ultra-compact footprint ideal for space-constrained camera modules and wearables. |
Pinout & Package
VL53L1CBV0FY/1 uses a 12-pin LGA (Land Grid Array) package with 0.5 mm pitch, optimized for single-reflow assembly and minimal PCB footprint. The module integrates analog and digital circuitry, requiring careful decoupling near AVDDVCSEL and AVDD pins per datasheet layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AVDDVCSEL | VCSEL Power Supply | Provides dedicated 2.6–3.5 V supply to the 940 nm laser emitter; must be decoupled locally to suppress switching noise. |
| 2 AVSSVCSEL | VCSEL Ground | Dedicated ground return path for VCSEL current; isolated from digital GND to minimize EMI coupling into SPAD array. |
| 3, 4, 6, 12 GND / GND2 / GND3 / GND4 | System Ground | Four independent ground terminals ensure low-impedance return paths for analog, digital, and VCSEL sections. |
| 5 XSHUT | Hardware Reset/Standby Control | Active-low input controlling hardware standby; drives device into ultra-low-power state when pulled low (AVDD remains active). |
| 7 GPIO1 | Interrupt Output | Open-drain output signaling measurement completion or threshold event; requires external 10 kΩ pull-up for I²C handshake synchronization. |
| 8 DNC | No Connect | Pin must remain floating; internal connection disabled - not usable for any signal or biasing function. |
| 9 SDA | I²C Data Line | Bi-directional serial data line supporting Fast Mode Plus (1 MHz); requires external pull-up resistor per bus topology. |
| 10 SCL | I²C Clock Line | Input-only clock line driven by host controller; timing compliant with I²C Fast Mode Plus specifications (tLOW ≥ 0.5 μs). |
| 11 AVDD | Digital Core Supply | Supplies microcontroller, firmware engine, and digital interface; shares voltage domain with AVDDVCSEL but requires separate decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Patented dToF Algorithms | Enables cover-glass crosstalk rejection >80 cm and multiobject separation within FoV - eliminates need for mechanical shutter or secondary sensors. |
| Configurable Multizone Scanning | Software-selectable ROI (2×2, 3×3, 4×4, or custom) - delivers mini-depth maps for touch-to-focus UX or stereoscopic dual-camera calibration. |
| Turnkey Driver Support | Linux® and Android-compatible C API with preset modes (ranging, multizone, lite, autonomous) - reduces integration time from weeks to hours. |
| Hardware Handshake Interface | XSHUT + GPIO1 enable deterministic power sequencing and interrupt-synchronized readouts - prevents missed measurements during high-speed scanning. |
| Class 1 Laser Compliance | Meets IEC 60825-1:2014 3rd edition without external optics or shielding - certified for integration into consumer devices with zero safety overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar time-of-flight ranging applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VL53L3CXV0FY/1 | Higher frame rate (up to 120 Hz), improved ambient light immunity (up to 100 klux), same LGA12 package and I²C interface. | Better suited for outdoor-facing applications or high-speed gesture recognition where lighting variability exceeds 60 klux. | Select if ambient light robustness >60 klux or sub-10 ms latency is required; otherwise VL53L1CBV0FY/1 offers optimal cost/performance balance. |
| TMD2635 | VCSEL-based proximity sensor with integrated ambient light sensing; lacks multizone capability and max range limited to 200 cm. | Targeted at basic proximity detection (e.g., phone call ear detection), not ranging or depth mapping. | Choose only for simple cover-open/close or screen blanking functions - not a functional substitute for dToF ranging or multiobject detection. |
Compared with VL53L3CXV0FY/1, the VL53L1CBV0FY/1 trades peak performance for lower power and cost in indoor-lit environments; versus TMD2635, it delivers true distance measurement rather than binary proximity, enabling focus control and depth-aware UIs.

FAQ
What is the default I²C address of the VL53L1CBV0FY/1, and can it be changed?
The VL53L1CBV0FY/1 ships with a fixed 7-bit I²C address of 0x52 (write) / 0x53 (read). This address is hard-coded in silicon and cannot be modified via software or hardware pin strapping. Multiple units on the same bus require individual addressing via GPIO-controlled XSHUT lines to enable sequential initialization.
Does the VL53L1CBV0FY/1 require external optical components like lenses or filters?
No external optics are required: the module integrates a molded plastic lens over the SPAD array and a bandpass filter matched to the 940 nm VCSEL emission. It is designed for direct mounting behind cover glass up to 5 mm thick, with patented algorithms compensating for optical crosstalk and smudge-induced signal degradation.
How does the autonomous mode operate without host intervention?
In autonomous mode, the on-chip firmware independently performs ranging at user-defined intervals (e.g., every 500 ms), compares results against programmable distance and signal thresholds, and asserts GPIO1 only when conditions are met - enabling ultra-low-power wake-on-proximity operation with no I²C traffic between events.
Is the VL53L1CBV0FY/1 compatible with Linux kernel drivers out of the box?
Yes - ST provides a production-ready Linux kernel driver (st-vl53l1) maintained in mainline kernel v5.10+, supporting sysfs interface, device tree binding, and full preset mode control. The driver abstracts register-level access and exposes calibrated distance, signal rate, and ROI data via standardized character device nodes.
