±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 detect for quick motion detection.
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
