概述

Description

The LIS2DUX12TR is STMicroelectronics’ 3‑axis MEMS accelerometer in the LIS2DUX family. It provides a digital output (I2C or SPI) for motion sensing in mobile, wearable, IoT, and embedded applications. Key points:
- 3‑axis sensing with programmable full‑scale ranges (typical options such as ±2 g, ±4 g, ±8 g, ±16 g) and programmable data rates.
- Low‑power modes with fast wake‑up to conserve battery life.
- Interrupts and embedded features for activity/inactivity, orientation, free‑fall, wake‑up, and tap events.
- Built‑in temperature sensor and robust packaging; “TR” typically denotes tape‑and‑reel packaging.
Common uses include device motion detection, gesture/tilt sensing, orientation sensing, and impact/motion logging in wearables, smartphones, gaming peripherals, and industrial sensors. For exact electrical specs and feature details, consult the latest ST datasheet for LIS2DUX12TR.

Features

LIS2DUX12TR features (concise):
- 3-axis MEMS accelerometer with 12-bit digital output
- Programmable full-scale: ±2/4/8/16 g
- I2C and SPI serial interfaces
- Adjustable data rate (ODR) from low to high (suitable for various sampling needs)
- Ultra-low-power modes plus high-performance mode
- Wide supply range: 1.62–3.6 V
- On-chip temperature sensor
- Rich interrupt capabilities: data-ready, free-fall, wake-up, activity/inactivity, single/double-tap, orientation
- FIFO buffer for event streaming
- Self-test and configurable filtering options
- Operating temperature range typically -40 to 105 °C (industrial)
- Package: small LGA footprint; Tape-and-Reel (TR) option available
Notes: packaging may be TR (tape-and-reel) variant as indicated by the part number.

Package

LIS2DUX12TR uses an LGA-12 package (3×3 mm); the trailing “TR” denotes Tape-and-Reel packaging.

Pinout

- Pin count: 16 pins (LGA-16 package; LIS2DUX12TR, Tape & Reel variant TR)
- Function: 3‑axis accelerometer with I2C/SPI serial interface. Power pins: VDD, VDDIO, GND. Communication pins: I2C (SCL, SDA) or SPI (SCK, SDI/MOSI, SDO/MISO, CS). Interrupt and status: INT1, INT2, DRDY. Additional control: RESET, BOOT (for reprogramming/boot).

Manufacturer

- Manufacturer: STMicroelectronics (STMicroelectronics N.V.)
- Kind of company: A global semiconductor and electronics company—multinational, designing, manufacturing, and marketing MEMS sensors, microcontrollers, power devices, and other semiconductor products.
