MMA8450Q

Low-power, 12-bit, 3-axis accelerometer

Simplifying complexity

The Freescale MMA8450Q is a 12-bit, 3-axis,

low g, I

with power as low as 27 uA in active mode,

contained in a small, low-profile 3 x 3 x 1 mm

QFN package. The MMA8450Q next-generation

motion sensing device provides 12-bit data with

first in, first out (FIFO) to accomplish complex

gesture recognition and position detection

required for next-generation mobile applications

that go beyond basic algorithms.

The MMA8450Q accelerometer provides

increased embedded intelligence such as

orientation, tap, double tap, jolt, freefall and

shake detection. Utilizing the embedded

functions in the MMA8450Q, customers can

develop more robust applications such as

position detection, 3-D gesture detection,

pedometry and many other next-generation

motion detection functions. The MMA8450Q

has two programmable interrupt pins,

making it possible to monitor two functions

independently. There are eight interrupt

sources that can be configured to use these

two independent interrupt pins. To operate with

C, digital capacitive acceleration sensor

extremely low power, the MMA8450Q has six

user configurable sample rates that can be set

over a wide range of 1.5 to 400 samples per

second where operating current is proportional
