LSM303AGRTR Description
The 3-axis digital linear acceleration sensor and 3-axis digital magnetic sensor are both included in the ultralow-power, high-performance system-in-package known as the LSM303AGR. The linear acceleration full scales of the LSM303AGR are 2g, 4g, 8g, and 16g, respectively, and its magnetic field dynamic range is 50 gauss. The LSM303AGR has an SPI serial standard interface in addition to 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).
The system can be set up to produce an interrupt signal for motion, magnetic field, and free-fall detection. The magnetic and accelerometer blocks can each be individually turned on or off.
