±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer

NXP Semiconductors. 

Freescale Semiconductor

Technical Data

±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). The MMA7456L includes a Standby Mode that makes it ideal for

handheld battery powered electronics.

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 and @ 8g in 10-Bit Mode)

• Selectable Sensitivity (±2g, ±4g, ±8g) for 8-bit Mode

• Robust Design, High Shocks Survivability (5,000g)

• RoHS Compliant

• Environmentally Preferred Product

• Low Cost

Typical Applications

• Cell Phone/PMP/PDA: Image Stability, Text Scroll, Motion Dialing, Tap to

Mute

• HDD: Freefall Detection

• Laptop PC: Freefall Detection, Anti-Theft

• Pedometer

• Motion Sensing, Event Recorder
