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?
