The LSM333D is an inertial module capable of providing 9 DOF (degrees of freedom) inertial sensing by combining a 3D accelerometer, a 3D gyroscope and a 3D magnetometer in a system-in-package.
The LSM333D has linear acceleration full-scales of ±2g/±4g/±8g/±16g, a magnetic field full-scale of ±2/±4/±8/±12 gauss and an angular rate of 250/±500/±2000 dps. All full-scales available are fully selectable by the user.
The LSM333D includes an I2C serial bus interface supporting standard and Fast mode 100 kHz and 400 kHz, and SPI serial standard interface.
The system can be configured to generate interrupt signals, on dedicated pins, motion and magnetic field detection. Thresholds and the timing of interrupt generators are programmable by the end user.
Magnetic, accelerometer and gyroscope sensing can be enabled or set in Power-down mode separately for smart power management.
The LSM333D is available in a plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
