3-axis orientation/motion detection sensor

the mma7660fc is a ±1.5g 3-axis accelerometer with digital output (i2c). it is a very low power, low profile capacitive mems sensor featuring a low pass filter, compensation for 0g offset and gain errors, and conversion to 6-bit digital values at a user configurable samples per second. the device can be used for sensor data changes, product  orientation, and gesture detection through an interrupt pin (int). the device is housed in a small 3mm x 3mm x 0.9mm dfn package.
