Product details
Overview
VL53L8CHV0GC/1 from STMicroelectronics is an AI-optimized 8×8 multizone Time-of-Flight (ToF) sensor with compact normalized histogram (CNH) output, 65° diagonal field of view, 2–400 cm ranging per zone, and dual I²C (1 MHz) / SPI (3 MHz) interface - deployed in coffee machine cup-rim detection, robotic floor sensing, gesture recognition, and people counting systems.
For engineers reviewing the VL53L8CHV0GC/1 datasheet, VL53L8CHV0GC/1 pinout, VL53L8CHV0GC/1 application, or VL53L8CHV0GC/1 equivalent, this page delivers verified technical context, validated pin functions, real-world AI-sensor use cases, and confirmed drop-in alternatives for embedded ToF system design.
Technical Context
The VL53L8CHV0GC/1 integrates a Class 1 940 nm VCSEL emitter, SPAD-based 64-zone receiving array, and on-module low-power microcontroller running ST's advanced ranging firmware. Its CNH data path delivers raw time-bin histograms up to 128 bins per zone with programmable bin width down to 37 mm.
It supports autonomous low-power mode with motion-triggered interrupts, configurable zone/bins/frequency trade-offs (e.g., 64 zones × 18 bins @ 15 Hz), and ambient IR level reporting per zone - enabling host-side AI inference without full waveform reconstruction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Field of View | 45° × 45° square (65° diagonal) detection volume - enables wide-area spatial coverage in compact form factor |
| Ranging Distance | 2–400 cm per zone - supports near-field object localization and long-range presence detection in same frame |
| Output Data Rate | Up to 30 Hz for full CNH + processed ToF data - sufficient for real-time hand posture or robotic navigation feedback loops |
| Interface Speed | I²C up to 1 MHz (address 0x52); SPI up to 3 MHz - ensures low-latency host polling and streaming of multizone histogram data |
| Supply Voltages | AVDD = 3.3 V (VCSEL/analog), CORE_1V8 = 1.8 V (core), IOVDD = 1.2 V or 1.8 V (I/O) - enables flexible power domain partitioning in mixed-voltage SoC designs |
| Operating Temperature | −30 °C to +85 °C - qualified for industrial robotics, smart home appliances, and automotive cabin sensing environments |
| Package | LGA16, 6.4 × 3.0 × 1.75 mm - surface-mount compatible with standard reflow profiles and minimal PCB footprint |
Pinout & Package
LGA16 package with exposed thermal pad (B4) requiring connection to ground plane for thermal conduction and EMI control. All digital signals referenced to IOVDD; AVDD powers analog circuitry and VCSEL; CORE_1V8 supplies internal core logic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (GPIO1) | General-purpose I/O / INT output | Open-drain interrupt output signaling motion or threshold events - defaults to tristate; requires 47 kΩ pullup to IOVDD |
| A2 (LPn) | I²C enable/disable control | Active-high logic input disabling I²C communication - used for address switching in multi-sensor systems |
| A3 (IOVDD) | I/O supply rail | Provides 1.2 V or 1.8 V to all digital I/O pins - must match host MCU voltage level for direct interfacing |
| A4 (SDA / MOSI) | Bidirectional data line | I²C data (bidirectional, 2.2 kΩ pullup required); SPI MOSI (input only) - shared physical pin, protocol selected via SPI_I2C_N |
| A5 (SCL / MCLK) | Clock input | I²C clock (input, 2.2 kΩ pullup required); SPI master clock (input) - rising edge samples data in SPI mode |
| C1 (SPI_I2C_N) | Protocol select / I²C reset | Pulldown to GND for I²C mode (active-low); pullup to IOVDD for SPI - toggling resets I²C target only, not full sensor |
| C2 (NCS) | SPI chip select | Active-low SPI enable - falling edge initiates transaction; rising edge terminates and resets internal state machine |
| C5 (MISO) | SPI data output | Push-pull output driven to IOVDD level - carries register read data or status during SPI transactions |
Key Features
| Feature | Design Value |
|---|---|
| Compact Normalized Histogram (CNH) Output | Delivers raw time-bin histograms (up to 128 bins, min 37 mm bin width) per zone - enables host-side ML model training on unprocessed ToF signal distributions |
| Configurable Multizone Resolution | Supports 64-zone (8×8), 32-zone, or 16-zone modes with corresponding histogram bin counts and frame rates - balances spatial resolution vs. temporal response for AI workload tuning |
| Autonomous Low-Power Mode | Hardware-interrupt-driven wake-up on motion or distance threshold crossing - eliminates continuous polling, reducing host CPU load and system power |
| Integrated VCSEL + Metasurface Optics | Class 1 940 nm VCSEL with DOE lenses delivering uniform 45°×45° FoV - eliminates external optics, simplifies cover glass integration, and ensures eye safety |
| Pin-to-Pin Compatibility | Direct replacement for VL53L8CX and driver-compatible with VL53L7CH - enables hardware reuse and firmware migration across ST's ToF product family |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multizone ToF sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VL53L8CX | Identical LGA16 pinout and CNH architecture; differs in factory calibration and default firmware configuration - no hardware change required. | Targeted at cost-sensitive consumer electronics where full 64-zone CNH bandwidth is not needed; lower max frame rate in high-resolution modes. | Select when leveraging existing VL53L8CX layout and seeking simplified qualification path with identical mechanical fit. |
| VL53L7CH | Same 8×8 zone count and CNH capability but limited to 32 bins maximum and 15 Hz max frame rate; shares driver API and register map. | Optimized for battery-powered devices requiring longer sleep intervals and reduced data throughput - e.g., smart doorbells or occupancy sensors. | Select when prioritizing ultra-low average power over histogram depth or motion responsiveness in AI inference pipelines. |
Compared with VL53L8CHV0GC/1, VL53L8CX offers identical hardware compatibility but less aggressive CNH timing, while VL53L7CH trades histogram resolution and frame rate for extended low-power operation - making VL53L8CH the optimal choice for real-time AI applications demanding full 128-bin, 30 Hz multizone streaming.

FAQ
What is the function of the SPI_I2C_N pin on VL53L8CHV0GC/1?
The SPI_I2C_N pin selects the communication protocol: pulled low (GND) enables I²C mode and serves as an active-high I²C reset; pulled high (IOVDD) enables SPI mode. Toggling it from low to high then back to low resets only the I²C interface - not the entire sensor - and does not affect ongoing ranging operations or firmware state.
Can VL53L8CHV0GC/1 operate with 1.2 V IOVDD and 1.8 V CORE_1V8 simultaneously?
Yes. The device supports independent 1.2 V IOVDD (for digital I/O) and 1.8 V CORE_1V8 (for analog core), provided both supplies meet minimum slew rate requirements (0.012 V/µs for CORE_1V8 and IOVDD). This allows integration with 1.2 V host interfaces while maintaining optimal analog performance.
How does the motion indicator feature work per zone?
The motion indicator is computed internally by comparing successive histogram frames per zone - detecting changes in signal amplitude distribution, peak shift, or bin occupancy variance. It outputs a binary flag per zone indicating motion occurrence, eliminating host-side delta computation and reducing latency in responsive applications like gesture triggers.
Is the thermal pad (B4) electrically connected to ground internally?
Yes. The thermal pad (B4) is internally connected to ground and must be soldered to a PCB ground plane. This provides both thermal dissipation for the VCSEL and EMI shielding for the sensitive SPAD array - failure to connect it degrades ranging accuracy, increases noise, and risks thermal shutdown during sustained high-frequency operation.
