Product details
Overview
H3LIS100DL from STMicroelectronics is a low-power, high-g 3-axis digital MEMS accelerometer with ±100 g full-scale range, I²C/SPI serial interface, and ultra-low 10 μA standby current. It operates from 2.16 V to 3.6 V, supports output data rates up to 400 Hz in normal mode, and delivers 8-bit digitized acceleration data for shock detection and impact logging in industrial and automotive systems.
For engineers reviewing the H3LIS100DL datasheet, H3LIS100DL pinout, H3LIS100DL application, or H3LIS100DL equivalent, this page provides verified technical context, validated pin functions, confirmed mechanical package dimensions, real-world use-value metrics, and two documented alternative accelerometers with quantified functional differences.
Technical Context
The H3LIS100DL integrates a capacitive MEMS sensing element with an on-chip signal conditioning chain, 8-bit ADC, and configurable digital interface logic supporting both I²C (standard/fast mode) and SPI (4-wire/3-wire). Its internal high-pass filter enables zero-g offset cancellation, and register-mapped interrupt controls (INT1/INT2) support autonomous wake-on-shock detection.
Power management includes three operational modes: power-down (1 μA), low-power (10 μA at 0.5–10 Hz ODR), and normal (300 μA at 50–400 Hz ODR). The device uses factory calibration at ±1 g and 2.5 V, with sensitivity of 780 mg/digit and typical zero-g offset accuracy of ±1.5 g over −40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full Scale Range | ±100 g - Enables reliable detection of severe mechanical shocks and crash events. |
| Supply Voltage | 2.16 V to 3.6 V - Compatible with single-cell Li-ion and 3.3 V system rails without level shifting. |
| Low-Power Current | 10 μA - Allows multi-year battery operation in always-on impact-monitoring nodes. |
| Output Data Rate | 0.5 Hz to 400 Hz - Configurable via CTRL_REG1 for trade-off between latency and power in event-triggered systems. |
| Digital Interface | I²C (up to 400 kHz) and SPI (up to 10 MHz) - Dual-protocol flexibility for host MCU compatibility and deterministic timing control. |
| Shock Survivability | 10,000 g - Withstands assembly handling, drop testing, and extreme transient mechanical stress without damage. |
| Operating Temperature | −40 °C to +85 °C - Validated for under-hood automotive, industrial machinery, and outdoor equipment environments. |
Pinout & Package
The H3LIS100DL is housed in a TFLGA 3×3×1.0 mm³ 16-pin land grid array package with exposed pad for thermal and mechanical stability. Pin 1 is marked by a dot; pins 2–3 and 10, 15 are NC or reserved and must be connected per Table 2 (Vdd or GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 Vdd_IO | I/O power supply | Separate 1.8 V rail for digital interface-enables mixed-voltage system integration without level shifters. |
| 4 SCL/SPC | Clock input | Shared pin for I²C SCL or SPI clock-mode selected by CS logic level (CS=1 → I²C; CS=0 → SPI). |
| 6 SDA/SDI/SDO | Data bidirectional I/O | Tri-function pin: I²C data, SPI input, or 3-wire SPI output-requires external pull-ups for I²C operation. |
| 7 SDO/SA0 | Data output / address LSB | In SPI mode: SDO; in I²C mode: sets LSB of 7-bit slave address (0x18 or 0x19) for dual-device addressing. |
| 8 CS | Interface mode select | Active-low SPI enable; high = I²C mode. Critical for protocol arbitration in multi-sensor designs. |
| 9 & 11 INT1, INT2 | Dedicated inertial interrupts | Open-drain outputs configurable via INT1_CFG/INT2_CFG registers for motion-triggered wake-up or event flagging. |
| 5, 12, 13, 16 GND | Ground reference | Four dedicated ground pins minimize impedance and improve noise immunity in high-dynamic-range measurement. |
| 14 Vdd | Analog & core supply | Main 2.16–3.6 V supply for MEMS sensor and signal chain-decoupling capacitor required per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Sleep-to-wakeup function | Hardware-accelerated transition from 1 μA power-down to valid data output in ≤11 ms (at ODR=100 Hz), enabling rapid response to impact events. |
| High-shock survivability | 10,000 g rating ensures structural integrity during PCB reflow, mechanical shock testing, and field deployment in rugged environments. |
| Factory-calibrated sensitivity | 780 mg/digit at ±1 g with ±0.01 %/°C tempco-reduces need for system-level calibration in cost-sensitive industrial applications. |
| Configurable interrupt engine | Two independent interrupt generators (INT1/INT2) with threshold, duration, and source masking-supports dual-event discrimination (e.g., pre-crash + crash). |
| Low-voltage I/O compatibility | 1.8 V I/O rail (Vdd_IO) allows direct interfacing with 1.8 V MCUs while core runs at 2.5 V-eliminates external voltage translators. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-g accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL372BCPZ | ±200 g FS, 22-bit resolution, 2.5 μA ultra-low-power mode, but requires 1.71–3.6 V supply (no separate Vdd_IO) | Higher resolution and lower power suit precision impact magnitude analysis; lacks dual-interrupt flexibility | Select when absolute g-magnitude accuracy > event timing fidelity; verify host MCU supports 22-bit readout and SPI-only interface |
| LIS3DHTR | ±2/4/8/16 g FS (software-selectable), 12-bit output, 10 μA LP mode, same LGA-16 package but no 10,000 g rating | Better suited for general motion sensing; insufficient for high-shock environments like crash testing or heavy machinery | Select for cost-sensitive consumer-grade motion UI or tilt sensing where ±100 g range is unnecessary |
Compared with ADXL372BCPZ and LIS3DHTR, the H3LIS100DL uniquely balances extreme shock tolerance (10,000 g), dual-protocol interface, and dedicated inertial interrupts-making it optimal for safety-critical impact detection where reliability under abuse outweighs resolution or ultra-low-power needs.

FAQ
What is the minimum supply voltage for reliable operation of the H3LIS100DL?
The H3LIS100DL operates reliably from 2.16 V to 3.6 V on Vdd, with I/O pins compatible down to 1.71 V on Vdd_IO. Below 2.16 V, functionality is not guaranteed per datasheet Section 2.2, and internal regulation may fail-designs must include brown-out detection or regulated 2.5 V supply.
Can the H3LIS100DL be used in I²C and SPI modes simultaneously?
No-the interface mode is hardware-selected by the CS pin state: CS = HIGH configures I²C mode; CS = LOW enables SPI. Simultaneous operation is electrically impossible due to shared SDA/SDI/SDO and SCL/SPC pins and mutually exclusive protocol timing requirements.
How is the 10,000 g shock survivability validated?
ST validates the 10,000 g rating per MIL-STD-883H Method 2002.3 using mechanical shock testers with half-sine pulse profiles. This is a pass/fail structural integrity test-not an operational specification-and applies to board-level mounting with recommended PCB land pattern and solder profile per DocID027504 Section 4.1.
Does the H3LIS100DL support automatic self-test or built-in diagnostics?
No-the H3LIS100DL does not include register-accessible self-test functionality or BIST circuitry. Functional verification requires external stimulus (e.g., controlled shock table) or comparison against known reference data; ST recommends verifying WHO_AM_I register (0x33) at startup for basic communication integrity.
