Ultra-compact high-performance eCompass IC (accelerometer & magnetometer)

The LSM303AGR is an ultra-low-power highperformance system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. The LSM303AGR has linear acceleration full scales of ±2g/±4g/±8g/?16g and a magnetic field dynamic range of ±50 gauss. The LSM303AGR includes an I2C serial bus interface that supports standard, fast mode, fast mode plus, and high-speed (100 kHz, 400 kHz, 1 MHz, and 3.4 MHz) and an SPI serial standard interface. The system can be configured to generate an interrupt signal for free-fall, motion detection and magnetic field detection. The magnetic and accelerometer blocks can be enabled or put into power-down mode separately. The LSM303AGR is available in a plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C. 3 magnetic field channels and 3 acceleration channels ±50 gauss magnetic dynamic range ±2/±4/±8/?16 g selectable acceleration full scales 16-bit data output SPI / I2C serial interfaces Analog supply voltage 1.71 V to 3.6 V Selectable power mode/resolution for accelerometer and magnetometer Single measurement mode for magnetometer Programmable interrupt generators for freefall, motion detection and magnetic field detection Embedded self-test Embedded temperature sensor Embedded FIFO ECOPACK®, RoHS and “Green” compliant
