MMA8451QR1

The MMA8451QR1 is a smart low-power three-axis capacitive micromachined Digital Accelerometer with 14 bits of resolution. 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 wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8451Q to monitor events and remain in a low-power mode during periods of inactivity.

• 14- and 8-bit digital output
• Two programmable interrupt pins for seven interrupt sources
• Automatic ODR change for auto-wake and return to sleep
• Orientation (portrait/landscape) detection with programmable hysteresis
• High pass filter data available per sample and through the FIFO
• Self-test
