± 2g/4g/8g, Low g, 12-bit 3-axis Accelerometer

Overview

This product is in “End of Life” status, we recommend FXLS8974CF or FXLS8967AF as a replacement.

The NXP^® MMA8452Q is a low-power, three-axis capacitive micromachined accelerometer with 12 bits of resolution, featuring:

Embedded functions with flexible user-programmable options, configurable to two interrupt pins
Embedded interrupt functions for overall power savings relieving the host processor from continuously polling data
User-selectable full scales of ±2g/±4g/±8g with high-pass filtered data as well as non-filtered data available real-time
Inertial wake-up 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

1.95 to 3.6-volt supply voltage
1.6 to 3.6-volt interface voltage
±2g/±4g/±8g dynamically selectable full-scale
Output data rates (ODR) from 1.56 Hz to 800 Hz
99 μg/√Hz noise
12-bit and 8-bit digital output
I²C digital output interface (operates to 2.25 MHz with 4.7 kΩ pull-up)
Two programmable interrupt pins for six interrupt sources
Three embedded channels of motion detection
- Freefall or motion detection: one channel
- Pulse detection: one channel
- Jolt detection: one channel
Orientation (portrait/landscape) detection with set hysteresis
Automatic ODR change for auto-wake and return to sleep
High pass filter data available real-time
Self test
RoHS compliant
Current consumption: 6 μA–165 μA
This product is included in NXP’s product longevity program, with assured supply for a minimum of 10 years after launch

eCompass applications
Static orientation detection (portrait/landscape, up/down, left/right, back/front position identification)
Notebook, eReader and laptop tumble and freefall detection
Real-time orientation detection (virtual reality and gaming 3-D user position feedback)
Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)
Motion detection for portable product power saving (auto-sleep and auto-wake for cell phone, PDA, GPS, gaming)
Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)
User interface (menu scrolling by orientation change, tap detection for button replacement
