Ultra-compact high-performance e-compass 3D accelerometer and 3D magnetometer module

The LSM303C is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor.

The LSM303C has linear acceleration full scales of ±2 g / ±4 g / ±8 g and a magnetic field full scale of ±16 gauss.

The LSM303C includes an I2C serial bus interface that supports standard and fast mode (100 kHz and 400 kHz) 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 LSM303C 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.
