ISM330DHCXTR, STMicroelectronics, Industrial‑Grade 6‑Axis IMU Inertial Measurement Unit

Brand: ST (STMicroelectronics)

Device Type**: Industrial‑Grade 6‑Axis IMU (Inertial Measurement Unit), integrating 3‑Axis Accelerometer + 3‑Axis Gyroscope

Suffix TR = Tape & Reel packaging, MPQ=5000 pcs per reel

## Key Parameters

Package**: LGA‑14L, 2.5×3.0×0.83 mm, SMD surface‑mount

Accelerometer Full‑scale Range**: ±2 / ±4 / ±8 / ±16 g, 16‑bit ADC

Gyroscope Full‑scale Range**: ±125 / ±250 / ±500 / ±1000 / ±2000 / ±4000 dps (High angular rate for high‑speed rotation applications)

Output Interface**: I2C, SPI, auxiliary SPI supported

Supply Voltage**: 1.71 V‑3.6 V

Operating Temperature**: ‑40 ℃ ~ +105 ℃ (Industrial wide temperature range)

FIFO Buffer**: Up to 9 KB, reduces MCU reading workload

On‑chip Hardware Resources**

1. MLC (Machine Learning Core)

2. FSM (Finite State Machine) for custom motion event configuration

3. Sensor Hub for connecting external sensors

4. Built‑in temperature sensor and self‑test function

**Embedded Event Detection**: Free‑fall, wake‑up, tilt, 6D/4D orientation, single‑tap / double‑tap, pedometer

**Features**: Always‑On low‑power architecture. Eliminates frequent host‑MCU polling; motion judgment is processed inside the chip.

## Function

Output raw acceleration and angular rate motion data to the MCU. Leveraging on‑chip MLC/FSM, the chip locally implements motion recognition, vibration detection and attitude estimation, lowering host‑MCU computing overhead. Suitable for battery‑powered devices.

Difference from consumer‑grade IMU: Industrial wide‑temperature capability, high shock resistance, maximum gyroscope range up to 4000 dps. Optimized for high‑speed rotation and harsh working conditions.
