LSM303DLMSensor module: 3-axis accelerometer and 3-axis magnetometer
The LSM303DLM is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor.
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.
