Functionality
The LIS302DL is a ultracompact, low-power, digital output 3-axis linear accelerometer
packaged in a LGA package. The complete device includes a sensing element and an IC
interface able to take the information from the sensing element and to provide a signal to the
external world through an I
Sensing element
A proprietary process is used to create a surface micro-machined accelerometer. The
technology allows to carry out suspended silicon structures which are attached to the
substrate in a few points called anchors and are free to move in the direction of the sensed
acceleration. To be compatible with the traditional packaging techniques a cap is placed on
top of the sensing element to avoid blocking the moving parts during the moulding phase of
the plastic encapsulation.
When an acceleration is applied to the sensor the proof mass displaces from its nominal
position, causing an imbalance in the capacitive half-bridge. This imbalance is measured
using charge integration in response to a voltage pulse applied to the sense capacitor.
At steady state the nominal value of the capacitors are few pF and when an acceleration is
applied the maximum variation of the capacitive load is in fF range.
IC interface
The complete measurement chain is composed by a low-noise capacitive amplifier which
converts into an analog voltage the capacitive unbalancing of the MEMS sensor and by
analog-to-digital converters.
The acceleration data may be accessed through an I
device particularly suitable for direct interfacing with a microcontroller.
The LIS302DL features a Data-Ready signal (RDY) which indicates when a new set of
measured acceleration data is available thus simplifying data synchronization in the digital
system that uses the device.
The LIS302DL may also be configured to generate an inertial Wake-Up and Free-Fall
interrupt signal accordingly to a programmed acceleration event along the enabled axes.
Both Free-Fall and Wake-Up can be available simultaneously on two different pins.
Factory calibration
The IC interface is factory calibrated for sensitivity (So) and Zero-g level (Off).
The trimming values are stored inside the device by a non volatile memory. Any time the
device is turned on, the trimming parameters are downloaded into the registers to be used
during the normal operation. This allows the user to use the device without further
calibration.
