Product details
Overview
VL53L7CXV0GC/1 from STMicroelectronics is an 8×8 multizone Time-of-Flight (ToF) distance sensor with 90° diagonal field of view, integrated SPAD array, 940 nm VCSEL emitter, and on-chip microcontroller. It delivers absolute distance per zone up to 350 cm, operates at 60 Hz frame rate, supports autonomous low-power wake-up via programmable interrupt threshold, and achieves cover glass crosstalk immunity beyond 60 cm using histogram-based algorithmic compensation - deployed in robotics SLAM and smart building occupancy sensing.
For engineers reviewing the VL53L7CXV0GC/1 datasheet, VL53L7CXV0GC/1 pinout, VL53L7CXV0GC/1 application, or VL53L7CXV0GC/1 equivalent, key selection criteria include 60° × 60° square FoV coverage, I²C address 0x52 compatibility, dual-supply flexibility (AVDD: 2.8 V/3.3 V; IOVDD: 1.8 V/2.8 V/3.3 V), LGA16 package thermal pad grounding, and pin-to-pin alignment with VL53L5CX for migration paths.
Technical Context
The VL53L7CXV0GC/1 implements ST's FlightSense™ ToF architecture with a metasurface diffractive optical element (DOE) enabling precise 60° × 60° square FoV projection and uniform 8×8 zone sampling. Its ranging core processes raw SPAD histograms per zone to compute absolute distance independent of target reflectance or color.
It integrates a low-power ARM® Cortex®-M0+ microcontroller running firmware that manages autonomous mode transitions, interrupt generation on zone-specific motion detection, and real-time crosstalk compensation. Power states include LP idle (0.1 µA IOVDD), HP idle (35 mA), and active ranging (50–80 mA), with strict AVDD/IOVDD sequencing requirements to prevent leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Field of View | 60° × 60° square (90° diagonal); enables full-frontal coverage without mechanical scanning in smart speakers or bin-level monitoring. |
| Ranging Range | 2–350 cm per zone; supports long-range obstacle detection in robotics and short-range user presence sensing in AR/VR. |
| Zone Resolution | 8×8 matrix (64 zones); allows spatially resolved multitarget tracking and motion vector analysis per zone. |
| Frame Rate | Up to 60 Hz; enables real-time focus optimization in video projectors and responsive gesture recognition. |
| Supply Voltages | AVDD: 2.8 V or 3.3 V; IOVDD: 1.8 V, 2.8 V, or 3.3 V; decoupling required per pin for stable ToF timing. |
| I²C Interface | Address 0x52, up to 1 MHz; supports auto-increment register access for efficient firmware-driven configuration. |
| Operating Temp. | −30 °C to +85 °C; validated for industrial robotics and outdoor smart lighting enclosures. |
Pinout & Package
VL53L7CXV0GC/1 is housed in a 6.4 mm × 3.0 mm × 1.6 mm reflowable LGA16 package with exposed thermal pad (B4) requiring direct connection to PCB ground plane for thermal stability and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (I2C_RST) | Digital input | Active-high I²C interface reset only; does not reset firmware state - used for bus recovery without full device reboot. |
| A3 (INT) | Digital I/O (open-drain) | Programmable interrupt output signaling zone motion or distance threshold breach; requires 47 kΩ pull-up to IOVDD. |
| A4 (IOVDD) | Power supply | Digital core and I/O voltage rail; must be powered same time or after AVDD to avoid leakage current. |
| A5 (LPn) | Digital input | Comms enable/disable control; drives I²C interface into high-impedance when low - essential for multi-sensor I²C address management. |
| B1/B7 (AVDD) | Power supply | Analog and VCSEL supply; dual AVDD pins reduce IR drop and improve pulse consistency for accurate ToF measurement. |
| C3 (SDA), C4 (SCL) | I²C bidirectional/data clock | Require 2.2 kΩ pull-ups to IOVDD; support 1 MHz Fast Mode Plus for rapid register writes during dynamic mode switching. |
| B4 (THERMALPAD) | Ground terminal | Mandatory thermal and electrical ground connection; insufficient soldering causes thermal drift and ranging instability. |
Key Features
| Feature | Design Value |
|---|---|
| Metasurface DOE optics | Enables 60° × 60° square FoV with <±1.5° angular uniformity - eliminates need for external lens calibration in compact designs. |
| Autonomous low-power mode | Sub-µA IOVDD current with zone-specific interrupt threshold triggering - extends battery life in always-on smart lighting nodes. |
| Histogram-based crosstalk compensation | Removes cover-glass-induced artifacts beyond 60 cm - enables reliable operation behind 5 mm tempered glass in vending machines. |
| Multi-target per zone detection | Resolves ≥2 objects within single 8×8 zone using temporal histogram separation - critical for floor-type classification in vacuum robots. |
| Pin-to-pin & driver compatibility with VL53L5CX | Same LGA16 footprint, identical I²C register map, and shared API - reduces redesign effort when upgrading from 4×4 to 8×8 resolution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multizone ToF ranging applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VL53L5CXV0GA/1 | 4×4 zone resolution, 64 cm max range, same LGA16 package and I²C register map. | Limited to shorter-range, lower-resolution use cases like basic gesture control or proximity wake-up. | Select when cost sensitivity outweighs need for 8×8 spatial fidelity or >200 cm range. |
| TMD2635 | Single-zone IR proximity sensor with ambient light rejection; no ToF, no multizone, no histogram processing. | Suitable only for binary presence detection - lacks depth matrix, motion vectors, or cover-glass compensation. | Choose only for ultra-low-cost, non-ranging applications where absolute distance or zone differentiation is unnecessary. |
Compared with VL53L5CXV0GA/1, the VL53L7CXV0GC/1 adds 4× more spatial resolution and 5.5× longer range, enabling new SLAM and content management functions; versus TMD2635, it replaces binary sensing with calibrated depth mapping - requiring different firmware architecture and calibration workflows.

FAQ
What is the minimum detectable object size per zone at 1 m distance?
The VL53L7CXV0GC/1 resolves objects ≥2 cm in diameter at 1 m when using 8×8 mode and default sharpener settings. This is determined by its 60° × 60° FoV mapped to 64 zones, yielding ~7.5° angular resolution per zone - sufficient for detecting fingers, small tools, or bin contents in industrial monitoring.
Can the sensor operate behind tinted or coated cover glass?
Yes - the 940 nm VCSEL emitter and SPAD receiver are optimized for transmission through common cover materials including 3–5 mm tempered glass, acrylic, and polycarbonate with anti-reflective or IR-pass coatings. ST's histogram algorithms actively suppress crosstalk up to 350 cm, validated per DS13865 Rev 8 test conditions.
Is the thermal pad (B4) electrically isolated or grounded?
The THERMALPAD (B4) is internally connected to GND and must be soldered to a dedicated PCB ground plane. Per AN5853, failure to establish low-impedance thermal grounding causes junction temperature rise >10°C, degrading ranging accuracy and increasing RMS error beyond ±3% at 200 cm.
Does autonomous mode support zone-specific interrupt thresholds?
Yes - each of the 64 zones can be individually configured with independent distance upper/lower thresholds and motion sensitivity levels. Interrupt assertion (via A3/INT pin) occurs only when the programmed condition is met in at least one enabled zone, allowing selective wake-up logic in host MCU firmware.
