ST LSM303AGRTR

加速计，磁力仪，温度，6 轴I²C，SPI-40°C ~ 85°C（TA）

Overview

The LSM303AGRTR is an ultra-low-power highperformance system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. The LSM303AGRTR has linear acceleration full scales of ±2g/±4g/±8g/16g and a magnetic field dynamic range of ±50 gauss. The LSM303AGRTR 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 LSM303AGRTR 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.
