Product details
Overview
ASM330LHBG1TR from STMicroelectronics is a 6-axis inertial measurement unit (IMU) integrating a 3-axis digital accelerometer (±2/±4/±8/±16 g full scale) and 3-axis digital gyroscope (±125 to ±4000 dps range), AEC-Q100 qualified and ASIL B compliant when used with certified ISO 26262 software library, operating from −40°C to +125°C for automotive dead-reckoning and V2X systems.
For engineers reviewing the ASM330LHBG1TR datasheet, ASM330LHBG1TR pinout, ASM330LHBG1TR application, or ASM330LHBG1TR equivalent, key selection criteria include its dual-mode operation (high-performance/low-power), embedded finite state machine (16 states), machine learning core (8 concurrent flows), 3 KB FIFO, and synchronized six-channel output for sensor fusion accuracy in ADAS and active suspension.
Technical Context
The ASM330LHBG1TR implements a tightly coupled accelerometer-gyroscope architecture with hardware-level data synchronization across all six axes, enabling precise time-aligned sampling for dead-reckoning algorithms. Its on-die compensation ensures ±100 ppm/°C linear acceleration sensitivity drift and ±70 ppm/°C angular rate sensitivity drift over −40°C to +125°C.
It integrates two independent programmable processing blocks: a finite state machine supporting up to 16 user-defined motion-state transitions (e.g., vehicle stationary/moving detection), and a machine learning core executing configurable "if-then-else" decision trees on filtered accelerometer/gyro data - both operating autonomously without host CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acceleration Range | ±2/±4/±8/±16 g - selectable full-scale enables optimal resolution/noise trade-off per application (e.g., ±2 g for high-precision tilt, ±16 g for crash detection) |
| Gyroscope Range | ±125 to ±4000 dps - wide dynamic range supports both low-speed stabilization (e.g., camera) and high-speed maneuver detection (e.g., lane change) |
| Output Data Rate | Accelerometer: 1.6–1667 Hz; Gyroscope: 12.5–1667 Hz - asynchronous ODR configuration allows independent optimization of latency vs. power |
| Current Consumption | Combo low-power mode: 530–1000 µA at 52 Hz - enables always-on motion sensing in battery-constrained telematics modules |
| Temperature Range | −40°C to +125°C - qualified for under-hood and chassis-mounted automotive locations without external thermal management |
| FIFO Depth | 3 KB embedded FIFO - reduces host processor polling frequency and interrupt load during continuous high-ODR streaming |
| Interface Support | I²C, MIPI I3C℠, SPI - multi-protocol compatibility simplifies integration into legacy (I²C) and next-gen (I3C) automotive domain controllers |
Pinout & Package
ASM330LHBG1TR is housed in a 14-pin LGA package (2.5 × 3.0 × 0.83 mm³) with exposed pad for thermal and mechanical stability in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SDO/SA0 | Serial data output / address LSB | Provides SPI data output or sets I²C/I3C slave address bit; enables multi-device bus addressing |
| 2–3 RES | Reset configuration | Hardwired to Vdd_IO or GND to select default reset behavior; no external pull required |
| 4 INT1 | Programmable interrupt 1 | Hardware-triggered event signal (e.g., free-fall, 6D orientation) reducing host polling overhead |
| 5 Vdd_IO | I/O power supply | Independent 1.62–3.6 V rail decoupled with 100 nF capacitor; isolates digital interface noise from analog core |
| 7 GND | Ground reference | Common 0 V return path for analog and digital sections; requires low-impedance PCB connection |
| 8 Vdd | Analog/digital core supply | Main 1.71–3.6 V supply with 100 nF + 10 µF decoupling; powers MEMS sensing elements and signal chain |
| 9 INT2/DEN | Interrupt 2 / data enable | Dual-function pin: generates secondary motion interrupts or acts as DEN for synchronized data capture |
| 12 CS | Interface mode select | Configures communication protocol: logic high = I²C/I3C enabled; logic low = SPI enabled |
| 13 SCL/SPC | Clock input | Accepts I²C/I3C clock (up to 1 MHz) or SPI clock (up to 10 MHz); timing-critical for deterministic sampling |
| 14 SDA/SDI/SDO | Data bidirectional | Tri-function pin: I²C/I3C data line, SPI input, or 3-wire SPI output - eliminates need for separate SDI/SDO lines |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Finite State Machine | 16 independent state machines enable real-time vehicle status detection (e.g., parked/moving) without host CPU cycles |
| Machine Learning Core | 8 concurrent decision flows with 512-node capacity allow on-sensor classification of driving patterns (e.g., braking, turning) at <10 µA added current |
| Six-Channel Synchronized Output | Hardware-aligned timestamping across all 6 axes eliminates inter-sensor skew critical for dead-reckoning position error <0.5%/min |
| ASIL B Compliance Ready | Delivered with ISO 26262-certified safety manual (AN5691) and software library - reduces functional safety validation effort by >40% for Tier 1 ADAS modules |
| Extended Temperature Stability | Accelerometer bias drift ≤±200 mg and gyroscope offset drift ≤±10 dps over −40°C to +125°C - maintains calibration integrity in engine bay mounting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-axis IMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LSM6DSRXTR | Same package and pinout; lacks ASIL B certification support and extended +125°C qualification; max gyro range ±2000 dps | Targeted at consumer-grade ADAS accessories (e.g., aftermarket dashcams), not safety-critical chassis control | Select when ASIL B compliance and >+105°C operation are unnecessary and cost is primary constraint |
| ICM-42688-P | Higher noise floor (125 µg/√Hz vs. 60 µg/√Hz); no embedded MLC or FSM; supports only I²C/SPI (no I3C) | Suitable for non-safety telematics but cannot replace ASM330LHBG1TR in dead-reckoning or V2X where on-sensor AI is required | Choose for basic motion sensing where host-side ML processing is available and thermal range ≤+105°C suffices |
Compared with LSM6DSRXTR and ICM-42688-P, the ASM330LHBG1TR uniquely delivers ASIL B readiness, +125°C operation, ±4000 dps gyro range, and dual on-sensor AI engines - making it the only option for production automotive dead-reckoning and active safety systems requiring functional safety certification.

FAQ
Is ASM330LHBG1TR pin-compatible with earlier ST IMUs like LSM6DSOX?
No. ASM330LHBG1TR uses a 14-pin LGA package with unique pin assignments including dual RES pins, dedicated INT2/DEN functionality, and shared SDA/SDI/SDO tri-mode operation - differing from LSM6DSOX's 16-pin LGA layout and signal mapping. Board redesign is required for migration.
What software tools support the machine learning core (MLC) configuration?
ST provides Unico GUI with MLC configuration wizard and ST's X-CUBE-MEMS1 firmware pack, enabling drag-and-drop decision tree creation, on-sensor training validation, and register-level code export. No third-party toolchain or cloud dependency is needed - full offline development is supported.
Does ASM330LHBG1TR require external temperature compensation for automotive use?
No. The device integrates factory-trimmed temperature compensation for both accelerometer and gyroscope sensitivity and offset, maintaining ±200 mg and ±10 dps accuracy across −40°C to +125°C - eliminating need for host-based calibration routines in production ECUs.
How is ASIL B compliance achieved given the device itself is hardware-only?
ASIL B compliance is achieved through co-certification: ST supplies ISO 26262:2018-certified safety manual (AN5691) and software library that implements diagnostic monitoring, fault injection testing, and safe state management - enabling integrators to meet ASIL B requirements when this library is deployed on a qualified host processor.
