Overview

The LSM6DST is a system-in-package featuring a high-performance 3-axis digital

accelerometer and 3-axis digital gyroscope.

The LSM6DST delivers best-in-class motion sensing that can detect orientation and

gestures in order to empower application developers and consumers with features and

capabilities that are more sophisticated than simply orienting their devices to portrait and

landscape mode.

The event-detection interrupts enable efficient and reliable motion tracking and contextual

awareness, implementing hardware recognition of free-fall events, 6D orientation, click and

double-click sensing, activity or inactivity, stationary/motion detection and wakeup events.

The LSM6DST supports main OS requirements, offering real, virtual and batch mode

sensors. In addition, the LSM6DST can efficiently run the sensor-related features specified

in Android, saving power and enabling faster reaction time. In particular, the LSM6DST has

been designed to implement hardware features such as significant motion detection,

stationary/motion detection, tilt, pedometer functions, timestamping and to support the data

acquisition of an external magnetometer.

The LSM6DST offers hardware flexibility to connect the pins with different mode

connections to external sensors to expand functionalities such as adding a sensor hub,

auxiliary SPI, etc.

Up to 9 kbytes of FIFO with compression and dynamic allocation of significant data (i.e.

external sensors, timestamp, etc.) allows overall power saving of the system.

Like the entire portfolio of MEMS sensor modules, the LSM6DST leverages the robust and

mature in-house manufacturing processes already used for the production of

micromachined accelerometers and gyroscopes. The various sensing elements are

manufactured using specialized micromachining processes, while the IC interfaces are

developed using CMOS technology that allows the design of a dedicated circuit which is

trimmed to better match the characteristics of the sensing element.

The LSM6DST is available in a small plastic land grid array (LGA) package of

2.5 x 3.0 x 0.83 mm to address ultra-compact solutions.
