±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer
The MMA7455L 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 (click) detect for quick motion detection. The 0g offset can be customer calibrated using assigned 0g registers and g-Select which allows for command selection for 3 sensitivities (2g/4g/8g). Zero-g offset and sensitivity are factory set and require no external devices. The MMA7455L includes a Standby Mode that makes it ideal for handheld battery powered electronics.
Features
• Digital Output (I2C/SPI) - 10-Bit at 8g Mode
• 3mm x 5mm x 1mm LGA-14 Package
• Low Current Consumption: 400 μA
• 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/Click 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)
• Robust Design, High Shocks Survivability (10,000 g)
• RoHS Compliant
• Environmentally Preferred Product
• Low Cost
Typical Applications
• Cell Phone/PMP/PDA: Image Stability, Text Scroll, Motion Dialing, E-Compass, Tap to Mute
• HDD: Freefall Detection
• Laptop PC: Freefall Detection, Anti-Theft
• Navigation and Dead Reckoning: Position Detection, Pedometer
• E-Compass Tilt Compensation
• 3D Gaming: Tilt and Motion Sensing, Event Recorder

ELECTRO STATIC DISCHARGE (ESD)
WARNING: This device is sensitive to electrostatic discharge.
Although the Freescale accelerometer contains internal 2000V ESD protection circuitry, extra precaution must be taken by the user to protect the chip from ESD. A charge of over 2000 volts can accumulate on the human body or associated test equipment. A charge of this magnitude can alter the performance or cause failure of the chip. When handling the accelerometer, proper ESD precautions should be followed to avoid exposing the device to discharges which may be detrimental to its performance.
