Overview

The LSM6DSV80X is a 6-axis system-in-package featuring a high-performance 3-axis digital low-g accelerometer

(16 g), a 3-axis digital high-g accelerometer (80 g), and a 3-axis digital gyroscope.

The LSM6DSV80X delivers best-in-class motion sensing that can detect high-intensity impacts in order to

empower developers to improve tracking in sports activities by accurately measuring both high and low

accelerations efficiently. Whether it is the high-intensity forces in sports or the movements in everyday tracking,

the LSM6DSV80X delivers consistent performance and valuable data for analysis.

The event-detection interrupts enable efficient and reliable motion tracking and context awareness, implementing

hardware recognition of free-fall events, 6D orientation, click and double-click sensing, activity or inactivity,

stationary/motion detection and wake-up events. Machine learning and finite state machine processing allow

moving some algorithms from the application processor to the LSM6DSV80X sensor, enabling consistent

reduction of power consumption.

The device supports the main OS requirements, offering real, virtual, and batch mode sensors. In particular, the

LSM6DSV80X is designed to detect significant motion tracking, stationary/motion states, tilt, pedometer functions,

timestamping and to support the data acquisition of external sensors.

The LSM6DSV80X offers hardware flexibility to connect the pins with different mode connections to external

sensors to expand functionalities such as adding a sensor hub.

Channel 1 is designed to track motion detection. Data are available on the output of the I²C / SPI / I3C for the

accelerometer and gyroscope with independent ODR and FS.

Channel 2 is designed for high-g applications with accelerometer processing and independent FS from ±32 g

to ±80 g.

Up to 4.5 KB of FIFO with compression and dynamic allocation of significant data (that is, external sensors,

timestamp, and so forth) allows overall power saving of the system.

The LSM6DSV80X embeds a sensor fusion low-power (SFLP) algorithm able to provide a 6-axis (accelerometer

+ gyroscope) game rotation vector represented as a quaternion. The X, Y, Z quaternion components are stored in

FIFO.

Like the entire portfolio of MEMS sensor modules, the LSM6DSV80X 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 device embeds advanced dedicated features like a finite state machine and data filtering for motion

processing.

The LSM6DSV80X is available in a small plastic, land grid array (LGA) package of 2.5 x 3.0 x 0.83 mm to address

ultracompact solutions.
