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
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
to the sample rate. The power scheme
contains normal mode and low-power mode,
allowing the customer to achieve optimal
power consumption targets.
