Description
The LSM320DL is a system-in-package featuring
a 3D digital accelerometer and a 2D digital
gyroscope.
The ST modules family uses a robust and mature
manufacturing process already used for the
production of micromachined accelerometers.

3D accelerometer sensor and 2D gyroscope sensor
Doc ID 018845 Rev 1
The various sensing elements are manufactured
using specialized micromachining processes,
while the IC interfaces are realized using a CMOS
technology that allows to design a dedicated
circuit which is trimmed to better match the
sensing element characteristics.
LSM320DL has a dynamic user selectable full-
scale acceleration range of ±2g/±4g/±8/±16g and
angular rate of ±250/±500/±2000 deg/sec.
The accelerometer and gyroscope sensors can
be either activated or put in low power/power-
down mode separately for application optimized
power saving.
The LSM320DL is available in a plastic land grid
array (LGA) package.
Several years ago ST successfully pioneered the
use of this package for accelerometers. Today, ST
has the widest manufacturing capability and
strongest expertise in the world for production of
sensors in a plastic LGA package.
