STMicroelectronics N.V. has extended its iNemo sensing family with the release of an inertial module boasting nine degrees of freedom. The LSM333D is a fully integrated sensor module that enables advanced movement and location-sensitive apps, location-based services (LBS) and indoor navigation on portable devices, stated the company.

The product combines a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetic sensor in a single package. The first module in the family, the LSM333D, allows smartphone designers to drive system integration in new products supporting advanced context-sensitive user features.


The LSM333D combines a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetic sensor.

According to the company, the sensor module simplifies product design and saves about 30 percent of PCB space compared to a discrete solution. Moreover, sensor-fusion software helps product designers enable indoor navigation, LBS, dead reckoning and advanced motion and position detection.

The LSM333D includes a built-in temperature sensor and smart power management for longer handset battery life. In addition, the module allows the choice of either I2C or SPI connection to the main system controller. It also features 2 to 12gauss selectable magnetic full-scale range, 2g to 16g selectable linear acceleration full-scale range and 250 to 2000dps selectable rotational acceleration full-scale range.

The LSM333D is available in a 3.5 x 6 x 1mm package, and will soon enter volume production in the 4 x 4 x 1mm package.
