The MMA7455L is a Digital Output (I2C/SPI), low power, low profilecapacitive micromachined accelerometer featuring signal conditioning, a lowpass filter, temperature compensation, self-test, configurable to detect 0gthrough interrupt pins (INT1 or INT2), and pulse detect for quick motiondetection. 0g offset and sensitivity are factory set and require no externaldevices. The 0g offset can be customer calibrated using assigned 0g registersand g-Select which allows for command selection for 3 acceleration ranges(2g/4g/8g). The MMA7455L includes a Standby Mode that makes it ideal forhandheld 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 CostTypical 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
