Description
The LSM303DLM is a system-in-package
featuring a 3D digital linear acceleration sensor
and a 3D digital magnetic sensor.
LGA-28L (5x5x1.0 mm)
The various sensing elements are manufactured
by using specialized micromachining processes,
while the IC interfaces are realized using a CMOS
technology that allows the design of a dedicated
circuit which is trimmed to better match the
sensing element characteristics. The
LSM303DLM has a linear acceleration full-scale
of ±2 g / ±4 g / ±8 g and a magnetic field full-scale
of ±1.3 / ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5.6 / ±8.1
gauss, both fully selectable by the user.
The LSM303DLM includes an I²C serial bus
interface that supports standard mode (100 kHz)
and fast mode (400 kHz). The system can be
configured to generate an interrupt signal by
inertial wakeup/free-fall events, as well as by the
position of the device itself. Thresholds and timing
of interrupt generators are programmable on the
fly by the end user.
Magnetic and accelerometer parts can be
enabled or put into power-down mode separately.
The LSM303DLM is available in a plastic land grid
array package (LGA), and is guaranteed to
operate over an extended temperature range from
-40 to +85 °C.
