The MMA7455LR1 is a 3-axis low power capacitive Micromachined Accelerometer features signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect zero-g through interrupt pins (INT1 or INT2) and pulse detect for quick motion detection. Zero-g offset and sensitivity are factory set and require no external devices. The zero-g offset can be customer calibrated using assigned zero-g registers and g-select which allows for command selection for three acceleration ranges (2g/4g/8g). The MMA745xL series includes a standby mode that makes it ideal for handheld battery-powered electronics.
Self-test for Z-axis
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
