Overview

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MMA7456L Rev 2, 10/2008 ±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer The MMA7456L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion detection.

0g offset and sensitivity are factory set and require no external devices.

The 0g offset can be customer calibrated using assigned 0g registers and g-Select which allows for command selection for 3 acceleration ranges (2g/4g/8g).

Key Features

  • Digital Output (I2C/SPI) 3mm x 5mm x 1mm LGA-14 Package Self-Test for Z-Axis Low Voltage Operation: 2.4 V.
  • 3.6 V User Assigned Registers for Offset Calibration Programmable Threshold Interrupt Output Level Detection for Motion Recognition (Shock, Vibration, Freefall) Pulse Detection for Single or Double Pulse Recognition Sensitivity (64 LSB/g @ 2g a.
