Document Number: MMA7361LC Freescale Semiconductor Rev 1, 08/2011 Data Sheet: Technical Data 1.5g, 6g Three Axis Low-g Micromachined Accelerometer MMA7361LC The MMA7361LC is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-Detect which detects linear freefall, and g-Select which allows for the selection between two sensitivities. Zero-g offset and sensitivity are factory set and require no external devices. The MMA7361LC: XYZ AXIS MMA7361LC includes a Sleep Mode that makes it ideal for handheld battery ACCELEROMETER powered electronics. 1.5g, 6g Features 3mm x 5mm x 1.0mm LGA-14 Package Low Current Consumption: 400 A Sleep Mode: 3 A Bottom View Low Voltage Operation: 2.2 V 3.6 V High Sensitivity (800 mV/g 1.5g) Selectable Sensitivity (1.5g, 6g) Fast Turn On Time (0.5 ms Enable Response Time) Self Test for Freefall Detect Diagnosis 0g-Detect for Freefall Protection Signal Conditioning with Low Pass Filter Robust Design, High Shocks Survivability 14 LEAD LGA RoHS Compliant CASE 1977-01 Environmentally Preferred Product Low Cost Typical Applications Top View 3D Gaming: Tilt and Motion Sensing, Event Recorder HDD MP3 Player: Freefall Detection N/C Laptop PC: Freefall Detection, Anti-Theft Cell Phone: Image Stability, Text Scroll, Motion Dialing, eCompass N/C SelfTest Pedometer: Motion Sensing N/C X OUT PDA: Text Scroll N/C Y Navigation and Dead Reckoning: eCompass Tilt Compensation OUT Robotics: Motion Sensing Z g-Select OUT V 0g-Detect SS V N/C ORDERING INFORMATION DD Temperature Package Part Number Package Shipping Sleep Range Drawing MMA7361LCT 40 to +85C 1977-01 LGA-14 Tray Figure 1.
