The MMA7660FC is a ±1.5 g 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 MMA7660FC has the built in capability to do orientation detection. This feature gives the customer the capability to do applications such as portrait/landscape in mobile phones/PMP/PDAs. The tilt orientation of the device is in 3 dimensions and is identified in its last known static position. This allows a product to set its display orientation appropriately to either portrait or landscape mode or to turn off the display when the device is placed upside down. The sensor provides 6 different positions: l
This application note discusses board mounting guidelines and considerations for the MMA7660FC sensor. The first topic that will be discussed is the minimum recommended footprint for surface mount applications. This is a critical portion of design and if not done properly can affect soldering connection interface between the board and the package. Next, will be soldering and mounting guidelines and considerations for the DFN accelerometer sensor to a PCB. These suggested methods will minimize the stress on
The MMA7660FC has the built-in capability to do orientation detection. This feature gives the customer the ability to do applications such as portrait/landscape in mobile phones/PMP/PDAs. The MMA7660FC provides 6 different positions: left, right, up, down, back, and front. The tilt orientation of the device is in 3 dimensions and is identified in its last know static position. The trip points for up/down/left/right occur at approximately 45 degrees from horizontal. The back/front interrupts occur at approxi
The MMA7660FC is a ±1.5 g 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 sample rate. The device can be used for sensor data changes, product orientation, shake detection, tap detection, and gesture detection through an interrupt pin (INT). This application note will describe how to set up the MMA7660FC registe
Offset calibration is very important for applications such as tilt for gaming and hand gesturing on mobile phones/PMP/PDA devices. There are a number of proponents when it comes to offset errors such as trim errors, mechanical stresses due to package and mounting, shifts due to temperature and aging. This application note will describe how to do offset calibration for the MMA7660FC with a Microcontroller.

We’ve put our expertise at your fingertips so it is easy to tailor our sensing capabilities for your needs.
NXP’s Sensor Toolbox offers a customizable selection of sensor development tools, accessories and software from NXP®.s portfolio of acceleration, magnetic, pressure and touch sensors. Sensors enrich designs with a broad range of capabilities in detecting real-world conditions. Target Applications: Altimeters, Barometry, Blood pressure monitors.
Our MMA7660FC three-axis low g I2C digital capacitive acceleration sensor operates with extremely low power at 47 uA. The device provides conversion to digital values at a user-configurable output data rate, offering proportional savings in supply current and power. The MMA7660FC accelerometer can be used for sensor data changes, product orientation and gesture detection through an interrupt pin.
Four Good Reasons to Use MMA7660FC Accelerometers. As more applications are requiring motion detection, the MMA7660FC features four key requirements such as digital output, small package, low power consumption and embedded intelligence.
