Product details
Overview
LSM330DL from STMicroelectronics is a system-in-package 6-axis inertial measurement unit (IMU) integrating a 3D digital accelerometer and a 3D digital gyroscope on a single die. It delivers ±2g/±4g/±8g/±16g acceleration full-scale ranges and ±250/±500/±2000 dps angular rate ranges, operates from 2.4–3.6 V analog supply and 1.8 V I/O, and supports SPI/I²C interfaces with programmable motion interrupts-used in GPS navigation systems and free-fall detection in portable electronics.
For engineers reviewing the LSM330DL datasheet, LSM330DL pinout, LSM330DL application, or LSM330DL equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes, real-world use-value metrics for orientation and motion sensing, and two documented alternative IMUs with explicit functional trade-offs.
Technical Context
The LSM330DL implements independent control paths for its accelerometer and gyroscope subsystems, each with dedicated registers (e.g., CTRL_REG1_A/G), selectable output data rates (ODR), and configurable high-pass filters. Both sensors share a common LGA-28 package but maintain separate power domains enabling selective low-power mode activation per sensor.
Its interrupt logic supports hardware-accelerated free-fall, click/double-click, and FIFO watermark events via INT1/INT2 pins, while factory-trimmed sensitivity and zero-level offsets ensure calibrated output without host-side compensation across temperature (−40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (Analog) | 2.4 V to 3.6 V - Enables direct connection to Li-ion battery rails or regulated 3.3 V supplies without external LDO. |
| Supply Voltage (I/O) | 1.8 V - Matches standard mobile SoC GPIO voltage levels, eliminating level-shifting requirements. |
| Acceleration Full-Scale | ±2g/±4g/±8g/±16g - User-selectable via CTRL_REG4_A register; higher ranges reduce resolution but increase shock survivability. |
| Angular Rate Full-Scale | ±250/±500/±2000 dps - Configured via CTRL_REG4_G; ±2000 dps supports fast rotational tracking in gaming controllers. |
| Interface Protocol | SPI (3-/4-wire) and I²C - Dual-mode support allows integration into either microcontroller ecosystem without protocol conversion. |
| Operating Temperature | −40°C to +85°C - Validated for industrial handhelds and automotive infotainment mounting locations. |
| Package | LGA-28, 7.5 × 4.4 × 1.1 mm - Surface-mount land grid array enables high-density PCB layout and robust mechanical attachment. |
Pinout & Package
LSM330DL uses a 28-pin plastic land grid array (LGA) package measuring 7.5 mm × 4.4 mm × 1.1 mm, optimized for compact portable devices and qualified for reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Analog power supply | Connects to 2.4–3.6 V source; powers MEMS sensing elements and analog front-end circuitry. |
| VDD_IO | Digital I/O supply | Supplies 1.8 V to SPI/I²C interface logic and register bank; decoupling required per datasheet Section 4.1. |
| GND | Ground reference | Common return path for analog and digital sections; requires low-impedance PCB plane connection. |
| SCL/SPC | I²C clock / SPI clock | Multiplexed pin: SCL in I²C mode, SPC in SPI mode; pulled high externally for I²C operation. |
| SDA/SDI | I²C data / SPI data in | Multiplexed bidirectional pin: open-drain I²C data line or SPI MOSI input. |
| SDO/SA0 | SPI data out / I²C address LSB | Configurable: outputs SPI data or sets I²C slave address bit (0x6A or 0x6B) when SA0 = low/high. |
| INT1 | Programmable interrupt output | Open-drain signal asserting free-fall, motion, FIFO, or click events; requires external pull-up resistor. |
| INT2 | Secondary interrupt output | Independent interrupt source for gyroscope-specific events (e.g., data-ready, overflow, FIFO threshold). |
Key Features
| Feature | Design Value |
|---|---|
| Independent sensor power control | Accelerometer and gyroscope can be powered down separately-enabling sub-10 µA standby current in motion-triggered wake-up designs. |
| Factory-calibrated offset & sensitivity | Zero-g and zero-dps offsets trimmed at production; eliminates need for runtime calibration in cost-sensitive consumer applications. |
| 6D orientation detection | Hardware-accelerated tilt calculation using combined accelerometer/gyroscope data-reduces host CPU load in UI rotation and screen auto-orientation. |
| Programmable high-pass filter | Configurable cutoff frequencies (e.g., 0.01 Hz to 1600 Hz) for accelerometer and gyroscope-enables vibration isolation or dynamic motion filtering. |
| FIFO buffer (accelerometer only) | 32-level FIFO stores X/Y/Z acceleration samples-allows burst reads and reduces I²C/SPI transaction overhead during continuous monitoring. |
Applications
| GPS Navigation Systems | Impact Recognition & Logging |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-axis IMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LSM9DS1 | Integrated magnetometer (3-axis), higher max ODR (952 Hz), supports embedded finite-state machine (FSM) for gesture recognition. | Better suited for compass-assisted navigation and complex motion classification (e.g., step counting, gesture ID). | Select when magnetic heading or on-sensor decision logic is required; adds 0.5 mA typical current vs. LSM330DL's 0.3 mA. |
| MPU-6050 | No factory calibration; requires host-side offset/sensitivity compensation; lower power-down current (5 µA vs. 10 µA). | Cost-optimized for mass-market wearables where calibration overhead is acceptable. | Choose for price-sensitive volume production where calibration infrastructure exists; lacks integrated FIFO for gyroscope data. |
Compared with LSM9DS1, LSM330DL offers lower power and simpler register mapping but omits magnetometer and FSM features; versus MPU-6050, it delivers plug-and-play accuracy at higher unit cost and slightly larger footprint.

FAQ
What communication interfaces does the LSM330DL support?
The LSM330DL supports both I²C and SPI protocols. I²C operates at standard (100 kHz) and fast (400 kHz) modes with slave address selectable via SA0 pin (0x6A or 0x6B). SPI supports 3-wire and 4-wire configurations with clock speeds up to 10 MHz, and all register reads/writes use 16-bit data words aligned to MSB-first format.
How is power managed between the accelerometer and gyroscope?
Power states are controlled independently through CTRL_REG1_A (accelerometer) and CTRL_REG1_G (gyroscope) registers. Each sensor supports normal, low-power, and power-down modes. For example, setting ODR = 0 in CTRL_REG1_A disables the accelerometer while leaving the gyroscope fully operational-enabling asymmetric power optimization in motion-triggered wake-up architectures.
Does the LSM330DL include built-in temperature compensation?
Yes-the LSM330DL integrates an on-die temperature sensor (OUT_TEMP_G register) and applies factory-trimmed coefficients to compensate accelerometer and gyroscope offset and sensitivity drift across −40°C to +85°C. No external calibration or host-side temperature correction is required for basic orientation or motion detection use cases.
Can the LSM330DL detect free-fall reliably in handheld devices?
Yes-free-fall detection is implemented in hardware via the accelerometer's interrupt engine. By configuring INT1_CFG_A to monitor all three axes for sustained low-g conditions (<0.5g for ≥100 ms), the device asserts INT1 within 10 ms of event onset. This meets IEC 60730 Class B timing requirements for safety-critical drop-response actions such as HDD spin-down.
