MMA8453QR1

The MMA8453QR1 is a 3-axis micro machined Accelerometer with 10 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. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing the MMA8453Q to monitor events and remain in a low-power mode during periods of inactivity. Three embedded channels of motion detection - Freefall or motion detection, pulse detection, jolt detection.

• 1.6 to 3.6V Interface voltage
• ±2g/±4g/±8g Dynamically selectable full scale
• Output data rates (ODR) from 1.56 to 800Hz
• 99μg/√Hz Noise
• 10-bit and 8-bit digital output
• Two programmable interrupt pins for six interrupt sources
• Orientation (portrait/landscape) detection with programmable hysteresis
• Automatic ODR change for auto-wake and return to sleep
• Current consumption 6 to 165μA
