Product details
Overview
LIS3DHHTR from STMicroelectronics is a high-resolution three-axis digital output MEMS accelerometer with ±2.5 g full-scale range, 45 μg/√Hz noise density, and embedded 12-bit temperature sensor. It delivers ultra-stable performance over temperature (<0.4 mg/°C) and time, features 16-bit acceleration data output via SPI 4-wire interface, and operates across –40 °C to +85 °C for precision inclinometer and antenna stabilization systems.
For engineers reviewing the LIS3DHHTR datasheet, LIS3DHHTR pinout, LIS3DHHTR application, or LIS3DHHTR equivalent, key selection criteria include its low-noise 45 μg/√Hz performance, FIFO depth of 32 levels, ceramic LGA-16 package (5×5×1.7 mm), SPI timing compliance up to 10 MHz, and integrated self-test capability for field validation.
Technical Context
The LIS3DHHTR implements a micromachined silicon sensing element paired with a CMOS interface IC trimmed to match sensor characteristics. Its signal chain includes configurable FIR/IIR filters (235 Hz or 440 Hz bandwidth), programmable FIFO modes (bypass, continuous, FIFO, continuous-to-FIFO), and dual interrupt outputs (INT1/INT2) triggered by FIFO threshold events.
It supports multiple operational modes via register-controlled configuration: self-test activation (ST1/ST2 bits), temperature sensor readout (OUT_TEMP_L/H registers), status monitoring (STATUS register), and power-up sequencing with defined Trise (0.01–100 ms) and Twait (0–10 ms) constraints between Vdd_IO and Vdd rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-scale range | ±2.5 g - Enables high-resolution tilt measurement with sub-millig-level resolution in precision leveling instruments. |
| Noise density | 45 μg/√Hz - Supports detection of sub-degree inclination changes in static or low-dynamic environments. |
| Output resolution | 16-bit digital - Provides 0.076 mg/digit sensitivity for fine-grained acceleration quantization. |
| Temperature stability | <0.4 mg/°C zero-g drift - Ensures minimal calibration drift across industrial temperature range (–40 °C to +85 °C). |
| FIFO depth | 32 levels - Buffers acceleration samples to reduce host processor polling overhead in burst-read applications. |
| SPI interface | 4-wire, up to 10 MHz - Enables deterministic, low-latency communication compatible with microcontroller SPI peripherals. |
| Operating voltage | 1.71–3.6 V (Vdd), 1.71–Vdd+0.1 V (Vdd_IO) - Supports direct interfacing with 1.8 V or 3.3 V logic domains without level shifters. |
Pinout & Package
The LIS3DHHTR is housed in a ceramic cavity land grid array (CC LGA-16) package measuring 5 mm × 5 mm × 1.7 mm, optimized for mechanical stress immunity and thermal stability in high-reliability motion sensing applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SPC) | SPI clock input | Master-generated clock synchronizing all SPI transfers; supports up to 10 MHz operation with defined setup/hold timing. |
| 2 (SDI) | SPI data input | Accepts register address and write data on falling SPC edge; requires 5 ns setup and 15 ns hold relative to SPC. |
| 3 (SDO) | SPI data output | Drives register read data starting at bit 8 of SPI frame; valid within 50 ns after SPC falling edge. |
| 4 (CS) | SPI chip select | Active-low enable; resets SPI state machine on de-assertion and defines transaction boundaries. |
| 5 (INT2), 6 (INT1) | Configurable interrupt outputs | Open-drain signals asserting on FIFO threshold events; support independent configuration via INT1_CTRL/INT2_CTRL registers. |
| 7 (Vdd_IO), 8 (Vdd) | Separate I/O and core supplies | Enables independent voltage domain control; requires decoupling (100 nF ceramic + 10 μF aluminum for Vdd). |
| 9 (GND) | Common ground reference | Primary return path for analog and digital circuits; pins 10–16 are reserved and must be connected to GND or left unconnected per layout guidelines. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-axis digital accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LSM6DSOXTR | 6-axis (3-axis accel + 3-axis gyro), higher ODR (6.6 kHz), lower noise (70 μg/√Hz), same LGA-16 package | Targets inertial measurement units (IMUs) requiring fused motion tracking, not pure tilt sensing | Select when angular rate data and sensor fusion are required; avoid if only high-stability DC acceleration is needed. |
| ADXL355BCPZ-RL7 | Analog output, ±2 g/±4 g/±8 g selectable FS, 25 μg/√Hz noise, 20-bit resolution, wider temp range (–40 °C to +125 °C) | Used in seismic monitoring and structural health applications demanding ultra-low noise and extended temperature operation | Select for analog-domain signal chains or >85 °C ambient environments; requires external ADC and more complex biasing. |
Compared with LIS3DHHTR, LSM6DSOXTR adds gyroscope functionality but trades off ultra-low noise for broader dynamic range and higher bandwidth, while ADXL355BCPZ-RL7 delivers superior noise performance at the cost of digital interface simplicity and industrial-grade temperature tolerance.

FAQ
What is the startup time for LIS3DHHTR after power-on?
The LIS3DHHTR requires 150 ms for cold-start initialization before valid acceleration data is available. This includes internal oscillator stabilization, sensor bias settling, and register reset completion. The recommended power-up sequence mandates controlled ramping of Vdd_IO before Vdd, with Trise between 0.01 ms and 100 ms and Twait up to 10 ms.
Does LIS3DHHTR support daisy-chain SPI configuration?
No, LIS3DHHTR does not support daisy-chain SPI. It implements a standard 4-wire SPI slave interface with dedicated CS, SPC, SDI, and SDO lines. Multiple devices require individual CS lines driven by the host controller; shared SPC/SDI/SDO buses are supported only with independent chip-select control.
How is the embedded temperature sensor calibrated?
The LIS3DHHTR's temperature sensor is factory-calibrated and provides 12-bit output (OUT_TEMP_L/H registers) with ±15 °C absolute accuracy and 16 digit/°C sensitivity. No user calibration is required; raw values map linearly to temperature with best-fit nonlinearity ≤5%, and RMS noise is 0.1 °C (RMS).
Can LIS3DHHTR operate with Vdd = 1.8 V and Vdd_IO = 3.3 V?
No - Vdd_IO must not exceed Vdd + 0.1 V per absolute maximum ratings. With Vdd = 1.8 V, Vdd_IO is limited to 1.9 V. To use 3.3 V I/O, Vdd must be set to ≥3.2 V. Simultaneous 1.8 V core and 3.3 V I/O operation violates electrical specifications and risks permanent damage.
