Product details
Overview
H3LIS100DLTR 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 from 0.5 Hz to 400 Hz, and delivers 8-bit digitized acceleration data for shock detection and impact logging in constrained-space industrial and automotive systems.
For engineers reviewing the H3LIS100DLTR datasheet, H3LIS100DLTR pinout, H3LIS100DLTR application, or H3LIS100DLTR equivalent, key selection criteria include its 10000 g shock survivability, sleep-to-wakeup latency, dual interrupt outputs (INT1/INT2), and TFLGA 3×3×1.0 mm³ 16-pin land grid array package compatibility with high-density PCB layouts.
Technical Context
The H3LIS100DLTR integrates a capacitive MEMS sensing element with an analog front-end, 8-bit ADC, and configurable digital signal path including programmable high-pass filter and interrupt logic. Its dual-mode operation-normal mode (up to 400 Hz ODR) and low-power mode (0.5–10 Hz)-is controlled via dedicated register bits (PM[2:0] in CTRL_REG1).
Communication is supported through either I²C (standard/fast mode, 100/400 kHz) or 4-wire/3-wire SPI (up to 10 MHz), with mode selected by the CS pin level. Interrupt generation is fully configurable per axis and threshold via INT1_CFG/INT2_CFG registers, enabling autonomous wake-up without host polling.
Key Specifications

Pinout & Package
The H3LIS100DLTR is housed in a 3×3×1.0 mm³ thin fine-pitch land grid array (TFLGA-16) package with 16 solder pads, optimized for space-constrained PCBs and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vdd_IO | I/O power supply rail - decoupled separately from core Vdd for noise isolation |
| 4 | SCL/SPC | Shared clock input - functions as I²C SCL or SPI SPC depending on CS state |
| 6 | SDA/SDI/SDO | Multi-function bidirectional data line - supports I²C SDA, SPI SDI, and 3-wire SDO |
| 7 | SDO/SA0 | Configurable output/address bit - SPI data out or LSB of I²C address (0x18/0x19) |
| 8 | CS | Interface mode select - high = I²C, low = SPI - also serves as chip select |
| 9, 11 | INT2, INT1 | Dedicated open-drain interrupt outputs - independently configurable for motion, shock, or wakeup events |
| 5, 12, 13, 16 | GND | Four ground connections - reduce impedance and improve noise immunity in high-g sensing |
| 14 | Vdd | Analog/digital core supply - must be decoupled with 100 nF ceramic capacitor near pad |
Key Features
| Feature | Design Value |
|---|---|
| Sleep-to-wakeup function | Enables autonomous transition from 1 μA power-down to active measurement within milliseconds upon threshold-triggered event |
| Dual independent interrupts | INT1 and INT2 support separate configurations (e.g., INT1 for free-fall, INT2 for shock) without host CPU intervention |
| Factory-calibrated sensitivity | 780 mg/digit at ±1 g - eliminates need for end-of-line calibration in most shock-detection applications |
| High-shock survivability | 10000 g rating ensures functional integrity after mechanical abuse during shipping, mounting, or field operation |
| Low-voltage I/O compatibility | 1.8 V tolerant I/Os allow direct interfacing with 1.8 V microcontrollers without level shifters |

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 μA typical LP current, integrated FIFO, SPI-only interface | Better suited for sustained high-bandwidth shock capture; lacks I²C option | Select when higher full-scale range and embedded data buffering are required over dual-interface flexibility |
| LSM303AGR | ±2/4/8 g FS, 2.5 μA LP current, integrated magnetometer, I²C-only | Optimized for tilt/orientation; insufficient for >10 g shock detection | Choose only for combined motion+compass applications where g-range requirements are ≤8 g |
Compared with ADXL372BCPZ and LSM303AGR, the H3LIS100DLTR uniquely balances ultra-high shock tolerance (10000 g), dual-protocol interface, and 10 μA low-power operation-making it optimal for cost-sensitive, space-constrained impact detectors needing guaranteed survivability and minimal host overhead.

FAQ
What is the minimum supply voltage required for reliable operation of the H3LIS100DLTR?
The H3LIS100DLTR operates reliably from 2.16 V to 3.6 V. Below 2.16 V, internal regulation fails and sensor output becomes invalid; operation at 2.16 V is confirmed in datasheet Table 4 and validated across temperature. The device does not support undervoltage lockout (UVLO) - external supervision is recommended if brownout risk exists.
Can the H3LIS100DLTR be used in I²C and SPI modes simultaneously?
No. Interface mode is determined solely by the logic level on the CS pin: high enables I²C, low enables SPI. Both protocols share pins (SCL/SPC, SDA/SDI/SDO), so concurrent operation would cause bus contention and undefined behavior. Mode switching requires resetting the device or reconfiguring CS with appropriate timing delays.
How is the 10000 g shock survivability verified for the H3LIS100DLTR?
The 10000 g rating is based on wafer-level mechanical stress testing per JEDEC JESD22-B110, including high-g shock pulses applied directly to the die. This specification reflects physical survivability-not functional accuracy-and is guaranteed across the full −40 °C to +85 °C operating range, as documented in Section 2.1 of the datasheet.
Does the H3LIS100DLTR require external calibration for shock detection applications?
No. The device undergoes factory calibration at ±1 g, yielding a typical sensitivity of 780 mg/digit and zero-g offset accuracy of ±1.5 g. For shock detection (threshold-based, not precision measurement), this calibration is sufficient; high-pass filtering can further suppress DC offset drift without external adjustment.
