Product details
Overview
VL53L8CXV0GC/1 from STMicroelectronics is an 8×8 multizone Time-of-Flight (ToF) sensor with FlightSense technology, delivering absolute distance measurement up to 400 cm per zone under ambient light, 65° diagonal field of view, and autonomous low-power wake-up via programmable interrupt. It integrates a 940 nm Class 1 VCSEL emitter, SPAD receiving array, and on-module microcontroller for histogram-based crosstalk compensation-enabling robust liquid level monitoring and robotic SLAM in compact industrial IoT devices.
For engineers reviewing the VL53L8CXV0GC/1 datasheet, VL53L8CXV0GC/1 pinout, VL53L8CXV0GC/1 application, or VL53L8CXV0GC/1 equivalent, this page delivers verified technical context on multizone ranging accuracy, SPI/I²C interface timing, cover glass immunity above 60 cm, and dual-voltage IOVDD support-critical for battery-powered presence detection and laser-assisted autofocus integration.
Technical Context
The VL53L8CXV0GC/1 implements a fully integrated ToF ranging core with hardware-accelerated histogram processing and patented algorithmic compensation for cover glass crosstalk. Its 64-zone depth map generation operates at up to 60 Hz frame rate using either I²C (1 MHz, address 0x52) or SPI (3 MHz, mode CPOL=1, CPHA=1) interfaces.
Power management includes LP idle state with RAM retention and fast resume to HP active ranging, controlled via dedicated LPn enable pin and SPI_I2C_N mode-select/reset pin. The sensor requires three independent supplies: AVDD (3.3 V), CORE_1V8 (1.8 V), and IOVDD (1.2 V or 1.8 V), with defined slew-rate constraints per supply to ensure reliable POR behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ranging Distance | 2–400 cm per zone; enables precise tank fill-level detection and cliff prediction in robotics without reflectance calibration. |
| Field of View | 65° diagonal detection volume; supports wide-area human presence sensing behind dark cover glass in smart lighting systems. |
| Zone Resolution | 8×8 configurable zones; allows motion vector tracking per zone for gesture recognition and AR/VR depth assistance. |
| Interface Speed | I²C up to 1 MHz, SPI up to 3 MHz; ensures sub-17 ms frame latency for real-time LAF (laser-assisted autofocus) in mobile cameras. |
| Emitter Wavelength | 940 nm VCSEL; Class 1 eye-safe IR illumination invisible to users, critical for unobtrusive user detection in consumer devices. |
| Operating Temp | −30 °C to +85 °C; validated for industrial embedded deployment in warehouse automation and outdoor IoT nodes. |
| Supply Voltages | AVDD = 3.3 V, CORE_1V8 = 1.8 V, IOVDD = 1.2 V or 1.8 V; supports flexible host voltage domain alignment without level shifters. |
Pinout & Package
LGA16 package, 6.4 × 3.0 × 1.75 mm, with exposed thermal pad (B4) requiring direct connection to PCB ground plane for thermal conduction and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (GPIO1) | Interrupt output / general-purpose I/O | Open-drain INT signal with 47 kΩ pullup to IOVDD; asserts on zone-specific threshold crossing for host wake-up without polling. |
| A2 (LPn) | I²C enable control | Active-high logic input disabling I²C communication when low; used for dynamic address switching in multi-sensor arrays. |
| A3 (IOVDD) | I/O power supply | Provides 1.2 V or 1.8 V rail for all digital interfaces; must match host IO voltage to avoid level-shifting circuitry. |
| A4 (SDA / MOSI) | Bidirectional data line | I²C data (bidirectional, 2.2 kΩ pullup required) or SPI MOSI input; shared pin reduces PCB routing complexity. |
| A5 (SCL / MCLK) | Clock input | I²C clock (2.2 kΩ pullup required) or SPI master clock; supports high-speed timing with tR/tF ≤ 120 ns (1 MHz mode). |
| C1 (SPI_I2C_N) | Interface mode select / reset | Pulldown to GND for I²C mode (active-low reset); pullup to IOVDD for SPI mode; toggle 0→1→0 resets I²C target only. |
| C2 (NCS) | SPI chip select | Active-low SPI enable; falling edge initiates transaction, rising edge terminates and resets internal command registers. |
| C5 (MISO) | SPI data output | Push-pull driven to IOVDD level; outputs register reads and status flags without external buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Multitarget per zone | Detects and reports up to 3 distinct targets within each of 64 zones using histogram analysis-enabling simultaneous person/object separation in smart bins. |
| Cover glass crosstalk immunity | Patented algorithmic compensation maintains >60 cm ranging accuracy through 2 mm black acrylic-eliminates mechanical bezel gaps in sleek device designs. |
| Autonomous low-power mode | LP idle state draws <10 µA while retaining RAM; wakes host via GPIO1 interrupt upon motion or distance threshold breach-extending battery life in wireless sensors. |
| Software-configurable FoV | Runtime selection between 4×4 and 8×8 zone modes via firmware API; balances resolution vs. frame rate for SLAM mapping or fast presence detection. |
| Laser-assisted autofocus (LAF) | Sub-10 cm precision at 60 Hz enables camera AF lock in <50 ms under 0.1 lux-critical for night-vision security cameras and low-light mobile photography. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VL53L5CXV0GA/1 | 4×4 zone resolution, 200 cm max range, identical LGA16 package and pinout. | Lower resolution and shorter range limit suitability to proximity-only use cases like display wake-up. | Select when cost sensitivity outweighs need for extended range or multitarget per zone. |
| TMD2635 | Single-zone IR proximity sensor with ambient light rejection; no histogram processing or VCSEL driver. | Cannot perform depth mapping or SLAM; limited to binary presence detection in consumer electronics. | Choose only for ultra-low-cost, single-target detection where multizone data is unnecessary. |
Compared with VL53L5CXV0GA/1 and TMD2635, the VL53L8CXV0GC/1 uniquely delivers 8×8 zone resolution, 400 cm ranging, and cover-glass-crosstalk immunity-making it the only option for industrial liquid level monitoring and robotic navigation requiring sub-centimeter depth fidelity.

FAQ
What is the maximum ambient light immunity specification for VL53L8CXV0GC/1?
The VL53L8CXV0GC/1 maintains full 400 cm ranging performance under 10 klux of ambient light, verified per DS14161 Rev 12 test conditions using 88% reflectance white target at 1 m distance. This immunity stems from its 940 nm VCSEL wavelength, advanced histogram processing, and algorithmic background subtraction-not optical filtering alone.
Can VL53L8CXV0GC/1 operate with only two power supplies instead of three?
No. The VL53L8CXV0GC/1 requires three independent supplies: AVDD (3.3 V), CORE_1V8 (1.8 V), and IOVDD (1.2 V or 1.8 V). While CORE_1V8 and IOVDD may share a 1.8 V rail, AVDD must remain isolated at 3.3 V to power the VCSEL driver and analog front-end-mixing supplies risks permanent damage or erratic ranging behavior.
Does VL53L8CXV0GC/1 support daisy-chaining multiple units on a single I²C bus?
Yes, but only with external I²C address modification. The default I²C address is fixed at 0x52; changing it requires driving the LPn pin to logic 0 during power-up and using ST's X-CUBE-TOF1 software to reprogram NVM. Hardware address pins are not provided-daisy-chaining demands firmware-level configuration per unit.
Is the thermal pad (B4) electrically connected to ground internally?
Yes. The exposed thermal pad (B4) is internally tied to the substrate ground plane. Per AN5897, it must be soldered to a dedicated PCB ground pour with ≥4 thermal vias (0.3 mm diameter) to ensure thermal dissipation below 45 °C junction rise and EMI compliance-failure to connect causes thermal shutdown and ranging drift.
