Document Number: MMA8452Q  
Rev. 5, 07/2012  
3-Axis, 12-bit/8-bit  
Digital Accelerometer  
MMA8452Q  
The MMA8452Q is a smart low-power, three-axis, capacitive micromachined  
accelerometer with 12 bits of resolution. This accelerometer is packed with  
embedded functions with flexible user programmable options, configurable to two  
interrupt pins. Embedded interrupt functions allow for overall power savings  
relieving the host processor from continuously polling data.  
Top and Bottom View  
The MMA8452Q has user selectable full scales of ±2g/±4g/±8g with high-pass  
filter filtered data as well as non-filtered data available real-time. The device can  
be configured to generate inertial wakeup interrupt signals from any combination  
of the configurable embedded functions allowing the MMA8452Q to monitor  
events and remain in a low power mode during periods of inactivity. The  
MMA8452Q is available in a 3 mm by 3 mm by 1 mm QFN package.
