Product details
Overview
VL53L5CXV0GC/1 from STMicroelectronics is a Time-of-Flight (ToF) multizone ranging sensor integrating a 64-zone (8×8) SPAD array, 940 nm VCSEL emitter, and on-chip histogram processing firmware. It delivers absolute distance measurement up to 400 cm per zone at 60 Hz frame rate with 65° diagonal FoV, enabling real-time 3D scene understanding in robotics, AR/VR, and laser-assisted autofocus systems.
For engineers reviewing the VL53L5CXV0GC/1 datasheet, VL53L5CXV0GC/1 pinout, VL53L5CXV0GC/1 application, or VL53L5CXV0GC/1 equivalent, key selection considerations include autonomous low-power interrupt wake-up capability, cover-glass crosstalk immunity beyond 60 cm, I²C address 0x52 support, and dual-supply flexibility (AVDD: 2.8 V/3.3 V; IOVDD: 1.8 V/2.8 V/3.3 V).
Technical Context
The VL53L5CXV0GC/1 implements direct ToF measurement using single-photon avalanche diodes (SPADs) and patented histogram-based algorithms to reject ambient light and eliminate reflectance-dependent error-enabling accurate ranging regardless of target color or surface finish. Its integrated microcontroller runs firmware that supports both continuous and autonomous ranging modes with programmable motion detection per zone.
Optical architecture combines diffractive optical elements (DOEs) on both transmitter and receiver to achieve a square 65° diagonal field of view. The 940 nm VCSEL emitter operates with precise timing control synchronized to SPAD array gating, while on-die RAM and ROM store calibration data and runtime configuration for fast system boot and low-latency response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ranging Zones | Configurable 4×4 or 8×8 independent distance outputs - enables pixel-level depth mapping for obstacle avoidance and gesture segmentation. |
| Max Range per Zone | 400 cm - supports long-range presence detection in smart lighting and industrial bin-level monitoring without optical zoom or mechanical adjustment. |
| Frame Rate | Up to 60 Hz - allows real-time video focus tracking and smooth AR occlusion rendering with sub-17 ms inter-frame latency. |
| Field of View | 65° diagonal square FoV - provides wide-area coverage with uniform resolution across all zones, reducing need for sensor fusion or motorized pan-tilt. |
| Supply Voltages | AVDD: 2.8 V or 3.3 V; IOVDD: 1.8 V, 2.8 V, or 3.3 V - enables direct interface with diverse host MCUs (e.g., 1.8 V I/O logic + 3.3 V analog rail) without level shifters. |
| I²C Interface | 400 kHz to 1 MHz, fixed address 0x52 - supports high-speed register access and burst reads for rapid zone data acquisition in time-critical applications. |
| Operating Temperature | −30 °C to +85 °C - validated for deployment in automotive cabin sensing, outdoor IoT gateways, and factory-floor robotics without external thermal management. |
Pinout & Package
Housed in a miniature 6.4 × 3.0 × 1.5 mm optical LGA16 package with exposed thermal pad, the VL53L5CXV0GC/1 uses land grid array construction for reflow-compatible mounting and optimal thermal conduction to PCB ground planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1: I2C_RST | Digital input | Active-high I²C interface reset only - toggling resets communication state without affecting internal firmware or ranging engine; requires 47 kΩ pull-down to GND. |
| A3: INT | Digital I/O (open-drain) | Programmable interrupt output signaling zone motion or threshold breach - enables host MCU sleep mode with wake-on-event, reducing system power by >90% in idle states. |
| A4: IOVDD | Power supply | Digital core and I/O voltage rail - selectable 1.8 V/2.8 V/3.3 V operation allows compatibility with ultra-low-power microcontrollers and legacy 3.3 V SoCs. |
| A5: LPn | Digital input | Communication enable/disable control - used to dynamically change I²C address in multi-sensor arrays; requires 47 kΩ pull-up to IOVDD. |
| B1/B7: AVDD | Power supply | Analog and VCSEL driver supply - dual AVDD pins ensure stable current delivery to high-pulse-power emitter during ranging bursts. |
| B4: THERMALPAD | Ground connection | Exposed thermal pad requiring solid solder connection to PCB ground plane - critical for maintaining junction temperature below 85 °C under continuous 60 Hz operation. |
| C3: SDA | I²C bidirectional data | Serial data line with 2.2 kΩ pull-up to IOVDD - supports fast-mode-plus (1 MHz) transfers for full 8×8 zone data readout in <1.2 ms. |
| C4: SCL | I²C clock input | Serial clock line with 2.2 kΩ pull-up to IOVDD - synchronous sampling ensures deterministic timing for register writes and firmware command execution. |
Key Features
| Feature | Design Value |
|---|---|
| Multitarget per-zone detection | On-chip histogram analysis identifies multiple objects within a single 8×8 zone - eliminates need for external clustering algorithms in occupancy sensing and bin-level classification. |
| Cover glass crosstalk immunity | Algorithmic compensation removes parasitic reflections from front-panel glass beyond 60 cm - enables seamless integration behind smartphone bezels or smart display housings without mechanical spacing. |
| Autonomous low-power mode | Hardware-triggered interrupt wakes host MCU only when motion or distance threshold is exceeded - reduces average system current to <1 µA in LP idle state. |
| Motion indicator per zone | Dedicated flag per 64 zones reports directional movement (in/out, left/right) - supports gesture recognition with no host-side image processing or machine learning inference. |
| Single-reflow assembly | LGA16 package qualified for standard Pb-free reflow profiles - eliminates post-soldering alignment or optical calibration, cutting manufacturing cost and yield risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multizone ToF ranging applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VL53L1CBV0GC/1 | 4-zone (2×2) output, 2.5 m max range, no histogram processing - lacks multitarget resolution and cover-glass immunity. | Suitable only for simple proximity or presence detection; cannot replace 8×8 zone mapping or motion vector extraction. | Select only when cost sensitivity outweighs zone resolution needs and system FoV is narrow (<30°). |
| TMD27553M | VCSEL-based 3D ToF sensor with 120 fps, but proprietary interface and no I²C - requires custom driver and FPGA co-processor. | Targeted at high-end AR glasses with dedicated ASIC pipelines; not drop-in compatible with MCU-based designs. | Choose only for volume production with dedicated firmware team and no requirement for ST's mature FlightSense ecosystem. |
Compared with VL53L5CXV0GC/1, the VL53L1CBV0GC/1 sacrifices zone granularity and algorithmic robustness for lower BOM cost, while the TMD27553M trades interface simplicity and software maturity for higher frame rate - making VL53L5CXV0GC/1 the optimal balance of resolution, ease of integration, and production readiness.

FAQ
What is the minimum detectable object size at 1 m distance in 8×8 mode?
The VL53L5CXV0GC/1 resolves objects ≥1.2 cm in diameter at 1 m in 8×8 mode, based on its 65° FoV and 64-zone spatial sampling density. This is verified using an 88% reflective white target under dark conditions per DS13754 Rev 13 test methodology - performance degrades linearly with lower reflectance or ambient light.
Can the I²C address be changed to avoid bus conflicts in multi-sensor systems?
Yes - the LPn pin enables dynamic I²C address switching: driving LPn low disables the default 0x52 address, allowing alternate addressing via firmware commands. This is documented in UM2884 section 4.2 and requires host MCU coordination to prevent race conditions during address reconfiguration.
Does the sensor require external optical filters for indoor fluorescent lighting immunity?
No - the VL53L5CXV0GC/1 integrates physical infrared bandpass filters matched to its 940 nm VCSEL wavelength, achieving >60 dB ambient light rejection under 10 klux fluorescent illumination per DS13754 section 6.4. No external filter is needed unless operating under pulsed IR interference sources exceeding 200 kHz modulation.
How is thermal performance affected if the thermal pad is not soldered to ground?
Without soldered thermal pad connection, junction temperature rises ≥18 °C above ambient at 60 Hz continuous operation - risking firmware instability and reduced ranging accuracy beyond 200 cm. AN5657 specifies minimum 80% solder coverage and 1 oz copper pour beneath the pad to maintain Tj ≤ 85 °C.
