Product details
Overview
VL53L4CDV0DH/1 from STMicroelectronics is a Time-of-Flight (ToF) proximity sensor IC designed for high-accuracy short-range distance measurement. It delivers absolute distance readings from 1 mm to 1200 mm with ±1 mm short-distance linearity, 18° diagonal field of view, and up to 100 Hz ranging frequency under ambient light - deployed in touchless faucets, robotic cliff detection, and liquid-level sensing in smart farming tanks.
For engineers reviewing the VL53L4CDV0DH/1 datasheet, VL53L4CDV0DH/1 pinout, VL53L4CDV0DH/1 application, or VL53L4CDV0DH/1 equivalent, key selection factors include its 55 µA ultralow-power (ULP) mode, I²C interface at 1 MHz, on-chip processing eliminating raw data transfer, and Class 1 940 nm VCSEL emitter enabling eye-safe operation behind cover glass.
Technical Context
The VL53L4CDV0DH/1 implements ST's FlightSense ToF architecture using a SPAD array and integrated 940 nm VCSEL driver. Its firmware performs full signal processing-including crosstalk compensation, ambient light rejection, and distance validation-outputting only validated range values via I²C.
It supports two power-up modes: hardware standby controlled by XSHUT (enabling true zero-power off-state), and software standby with automatic boot. The GPIO1 interrupt pin provides hardware-synchronized result notification, reducing host MCU polling overhead and ensuring no measurement loss during host latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Measuring Range | 1 mm to 1200 mm full FoV; enables single-sensor deployment across near-field activation and mid-range obstacle detection |
| Accuracy | ±1 mm linearity down to 1 mm; eliminates calibration drift in precision touchless switches and thermostats |
| Field of View | 18° diagonal FoV; balances detection area and optical crosstalk control for cover-glass-integrated designs |
| Power Consumption | 55 µA in ULP mode; extends battery life beyond 1 year in AA-powered access control and sanitary dispensers |
| I²C Interface | Up to 1 MHz (Fast Mode Plus); supports high-throughput multi-sensor bus configurations without timing bottlenecks |
| Operating Voltage | 2.6 V to 3.5 V; compatible with standard 2.8 V LDO rails and avoids need for level-shifting in 3.3 V systems |
| Ambient Temp Range | −30 °C to +85 °C; qualified for industrial enclosures, outdoor smart housing, and rice paddy monitoring units |
Pinout & Package
VL53L4CDV0DH/1 is housed in a miniature reflowable Optical LGA12 package measuring 4.4 × 2.4 × 1 mm, with exposed die and integrated VCSEL optics optimized for cover-glass mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AVDDVCSEL | VCSEL power supply | Must be decoupled locally; powers laser diode and analog front-end independently from digital core |
| 2 AVSSVCSEL | VCSEL ground | Separate analog ground return path prevents noise coupling into sensitive ToF timing circuitry |
| 3 GND / 4 GND2 / 6 GND3 / 12 GND4 | System ground | Four dedicated ground pins ensure low-impedance return paths and suppress EMI-induced measurement jitter |
| 5 XSHUT | Digital input (active-low) | Hardware shutdown control; enables true zero-current state and deterministic wake-up sequencing |
| 7 GPIO1 | Open-drain interrupt output | Signals valid measurement completion; eliminates polling and synchronizes host read with internal timing engine |
| 8 DNC | No-connect | Internally unused; must remain floating - not tied to VDD or GND to avoid leakage or latch-up |
| 9 SDA | I²C bidirectional data | Supports Fast Mode Plus (1 MHz); requires external 1 kΩ–1.5 kΩ pull-up for reliable high-speed bus operation |
| 10 SCL | I²C clock input | Driven by host; timing compliant with I²C spec up to 1 MHz with CL ≤ 140 pF |
| 11 AVDD | Digital core supply | Supplies microcontroller and digital logic; shares voltage rail with AVDDVCSEL in most compact designs |
Key Features

FAQ
What is the minimum detectable distance and linearity specification?
The VL53L4CDV0DH/1 achieves ±1 mm linearity starting from 1 mm distance, verified per DS13812 Rev 8 test conditions. This is enabled by on-chip calibration and advanced histogram processing - not extrapolated from longer-range data. It supports true millimeter-precision applications such as tactile switch emulation and robotic end-effector positioning.
Does it require external optical filtering for sunlight immunity?
No external optical filter is required. The 940 nm VCSEL emitter and matched SPAD array provide inherent ambient light rejection up to 100 klux, validated in DS13812 Section 6.2. Performance remains stable under direct sunlight exposure when used with standard 1 mm cover glass - confirmed via ST's outdoor characterization reports.
How is liquid level measurement implemented without custom firmware?
Liquid level functionality is delivered via STSW-IMG039, an officially supported firmware extension that configures internal ranging modes, applies material-specific correction algorithms, and outputs calibrated height values - all running on the on-chip microcontroller without host intervention or additional processing resources.
Can multiple VL53L4CDV0DH/1 sensors share one I²C bus?
Yes, up to four sensors can operate on a single I²C bus using hardware address configuration via the XSHUT pin during initialization. Each device is assigned a unique 7-bit address (0x52 default); alternate addresses 0x53, 0x54, and 0x55 are supported through sequential reset and reconfiguration sequences documented in UM2931.
