Introduction

AI Translation

The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. The MMA8452Q has user selectable full scales of ± 2 g / ± 4 g / ± 8 g with high-pass filtered data as well as non-filtered data available real-time. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing the MMA8452Q to monitor events and remain in a low-power mode during periods of inactivity. The MMA8452Q is available in a 16-pin QFN, 3 mm × 3 mm × 1 mm package.

Features

AI Translation
  • 1.95 V to 3.6 V supply voltage
  • 1.6 V to 3.6 V interface voltage
  • ± 2 g / ± 4 g / ± 8 g dynamically selectable full-scale
  • Output data rates (ODR) from 1.56 Hz to 800 Hz
  • 99 μg/√Hz noise
  • 12-bit and 8-bit digital output
  • I²C digital output interface
  • Two programmable interrupt pins for six interrupt sources
  • Three embedded channels of motion detection: Freefall or motion detection: one channel; Pulse detection: one channel; Transient detection: one channel
  • Orientation (portrait/landscape) detection with set hysteresis
  • Automatic ODR change for auto-wake and return to sleep
  • High-pass filter data available real-time
  • Self-test
  • Current consumption: 6 μA to 165 μA

Applications

AI Translation
  • E-compass applications
  • Static orientation detection (portrait/landscape, up/down, left/right, back/front position identification)
  • Notebook, e-reader, and laptop tumble and freefall detection
  • Real-time orientation detection (virtual reality and gaming 3D user position feedback)
  • Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)
  • Motion detection for portable product power saving (auto-sleep and auto-wake for cell phone, PDA, GPS, gaming)
  • Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)
  • User interface (menu scrolling by orientation change, pulse detection for button replacement)
