LSM303D Ultra-compact high-performance eCompass module: 3D accelerometer and 3D magnetometer Datasheet - production data Display orientation Gaming and virtual reality input devices Impact recognition and logging Vibration monitoring and compensation Description LGA-16 (3x3x1 mm) The LSM303D is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. The LSM303D has linear acceleration full scales Features of 2g / 4g / 6g / 8g / 16g and a magnetic 3 magnetic field channels and 3 acceleration field full scale of 2 / 4 / 8 / 12 gauss. channels 2 The LSM303D includes an I C serial bus 2/4/8/12 gauss magnetic full scale interface that supports standard and fast mode (100 kHz and 400 kHz) and SPI serial standard 2/4/6/8/16 g linear acceleration full scale interface. 16-bit data output 2 The system can be configured to generate an SPI / I C serial interfaces interrupt signal for free-fall, motion detection and Analog supply voltage 2.16 V to 3.6 V magnetic field detection. Thresholds and timing of Power-down mode / low-power mode interrupt generators are programmable by the end user. Programmable interrupt generators for free- fall, motion detection and magnetic field Magnetic and accelerometer blocks can be detection enabled or put into power-down mode separately. Embedded temperature sensor The LSM303D is available in a plastic land grid Embedded FIFO array package (LGA) and is guaranteed to operate over an extended temperature range ECOPACK , RoHS and Green compliant from -40 C to +85 C.
