Product details
Overview
LIS3DH from STMicroelectronics is an ultra-low-power, high-performance 3-axis MEMS digital accelerometer in the "nano" family, serving as a motion-sensing front-end for portable and battery-powered systems. It delivers 16-bit output resolution, ±2g/±4g/±8g/±16g dynamically selectable full-scale ranges, and supports I²C/SPI interfaces - enabling precise orientation detection, free-fall response, and click/double-click recognition in handheld consumer electronics.
For engineers reviewing the LIS3DH datasheet, LIS3DH pinout, LIS3DH application, or LIS3DH equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes (including low-power mode down to 2 μA), and real-world use cases in pedometers, display orientation, impact logging, and VR input devices.
Technical Context
The LIS3DH integrates a capacitive MEMS sensing element with a low-noise signal conditioning chain and configurable digital interface logic. Its dual interrupt generators support independent motion-triggered wake-up and free-fall detection, with programmable thresholds and duration windows via dedicated registers (e.g., INT1_CFG, INT2_THS).
It embeds a 32-level FIFO buffer for burst-mode data capture, reducing host processor polling overhead, and includes auxiliary ADC channels plus an integrated temperature sensor (±1 °C accuracy) for environmental compensation - all operating across –40 °C to +85 °C with 1.71 V–3.6 V supply voltage compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.71 V to 3.6 V - enables direct integration into Li-ion and coin-cell powered systems without external regulators. |
| Current Consumption (Low-Power Mode) | 2 μA - extends battery life in always-on motion-detection applications like smartwatches and remote controls. |
| Full-Scale Range | ±2g / ±4g / ±8g / ±16g - user-selectable via CTRL_REG4 register to optimize resolution vs. dynamic range per use case. |
| Output Resolution | 16-bit - provides sub-mg sensitivity (e.g., 0.98 mg/LSB at ±2g) for high-precision tilt and vibration analysis. |
| Data Output Rate | 1 Hz to 5.3 kHz - supports both slow-motion monitoring (e.g., structural health) and fast-event capture (e.g., impact shock). |
| FIFO Depth | 32 levels × 16-bit - buffers up to 96 bytes of X/Y/Z data, allowing host MCU to read batches instead of polling continuously. |
| Shock Survivability | 10,000 g - ensures mechanical robustness during drop testing and high-G industrial handling. |
Pinout & Package
The LIS3DH is housed in a 3 mm × 3 mm × 0.85 mm LGA-16 package with exposed pad for thermal dissipation and mechanical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply | Accepts 1.71–3.6 V; powers internal analog and digital blocks including MEMS transducer and ADC. |
| VDD_IO | IO supply voltage | Independent 1.8 V supply for digital interface pins (SDA/SCL/MOSI/MISO), enabling level-shifting with 1.8 V host systems. |
| GND | Ground reference | Common return path for analog and digital domains; must be connected to PCB ground plane under exposed pad. |
| SCL / SDA | I²C clock/data lines | Support standard/fast-mode I²C (up to 400 kHz); SDA is open-drain, requires external pull-up. |
| CS | Chip select | Active-low SPI enable; when high, device enters standby and draws <1 μA - critical for ultra-low-power sequencing. |
| SDO/SA0 | Slave address select / data output | Configures I²C address (0x18 or 0x19) or serves as SPI MISO; internal pull-up enables default address setting without external resistor. |
| INT1 / INT2 | Programmable interrupt outputs | Open-drain outputs driven by independent event engines - e.g., INT1 for free-fall, INT2 for 6D orientation change. |
Key Features
| Feature | Design Value |
|---|---|
| 6D/4D orientation detection | Identifies device position (up/down/left/right/front/back) using threshold-based vector comparison - enables automatic screen rotation without gyroscope fusion. |
| Embedded self-test | Electrostatic actuation verifies MEMS element integrity and signal chain functionality at power-on or runtime - eliminates need for external test fixtures. |
| Click/double-click recognition | Dedicated hardware engine detects tap events with configurable latency, window, and threshold - reduces firmware load in UI gesture implementations. |
| Temperature-compensated operation | On-chip temperature sensor (±1 °C) feeds calibration data to internal offset correction logic - maintains accuracy across –40 °C to +85 °C ambient range. |
| High-shock survivability | Rated for 10,000 g mechanical shock - survives board-level reflow, drop tests, and transport stress without parameter shift or failure. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis MEMS accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL345 | Fixed 13-bit resolution; no embedded temperature sensor; max ODR = 3.2 kHz; lacks 6D/4D orientation logic. | Requires external host-side orientation calculation; less suitable for low-power always-on orientation tasks. | Choose ADXL345 only if legacy design reuse or SPI-only interface is mandatory and temperature compensation is handled externally. |
| FXAS21002C | Gyroscope-only device; no accelerometer function; requires companion accelerometer (e.g., FXOS8700) for 6D detection. | Cannot replace LIS3DH standalone - only viable in IMU fusion designs where angular rate is primary requirement. | Select FXAS21002C only when angular velocity measurement dominates over linear acceleration in the system architecture. |
Compared with ADXL345 and FXAS21002C, the LIS3DH uniquely combines ultra-low-power operation (2 μA), on-device 6D orientation, embedded temperature sensing, and FIFO buffering - making it optimal for battery-constrained, self-contained motion-aware endpoints without host computational overhead.

FAQ
What is the minimum supply voltage for reliable LIS3DH operation?
The LIS3DH operates reliably from 1.71 V to 3.6 V. Below 1.71 V, internal voltage regulators and ADC references become unstable, causing data corruption and interrupt misfires. Testing confirms consistent 16-bit output and FIFO functionality only above 1.71 V across –40 °C to +85 °C.
How does the LIS3DH handle I²C address selection?
The LIS3DH uses the SDO/SA0 pin to set its I²C slave address: pulled low → 0x18; pulled high → 0x19. Internal pull-up (100 kΩ typical) ensures default 0x19 operation if left unconnected - eliminating need for external resistors in single-device configurations.
Can the LIS3DH generate interrupts for both free-fall and orientation change simultaneously?
Yes - INT1 and INT2 are fully independent. INT1 can be configured for free-fall detection (using ACT_THS/ACT_DUR registers), while INT2 can trigger on 6D orientation change (via CTRL_REG5 and INT2_CFG). Both interrupts assert concurrently without conflict or priority arbitration.
Is the LIS3DH RoHS and REACH compliant?
Yes - the LIS3DHTR variant is ECOPACK® certified, RoHS-compliant (2011/65/EU), and "Green" qualified (halogen-free, lead-free, and antimony-free per ST's material declarations). Full compliance documentation is available in ST's official product change notices and declarations of conformity.
