Description

The LSM303AGR is an ultra-low-power high-

performance 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.
