MMA8451Q datasheet



The MMA8451Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 14 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.

There is access to both low-pass filtered data as well as high-pass filtered data, which minimizes the data analysis required for jolt detection and faster transitions. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing the device to monitor events and remain in a low-power mode during periods of inactivity.


• Two programmable interrupt pins for seven interrupt sources
• Three embedded channels of motion detection
• Freefall or Motion Detection: 1 channel
• Pulse Detection: 1 channel
• Jolt Detection: 1 channel
• Orientation (Portrait/Landscape) detection with programmable hysteresis
• Automatic ODR change for Auto-WAKE and return to SLEEP
• 32-sample FIFO
