High performance 3D digital accelerometer and 3D digital gyroscope SIP

Update: May 18, 2021

STMicroelectronics LSM6DSO32XTR iNEMO Inertial Module, available now from Mouser, is a 3D digital accelerometer and 3D digital gyroscope SIP, with a digital I2C, SPI, and MIPI I3CSM serial interface standard output, working at 0.55mA in combo high-performance mode. Due to the ultra-low noise performance of the gyroscope and the accelerometer, the device couples always-on low-power features with superior sensing precision for an optimal motion experience in wearable, navigation, hard-fall detection, and asset tracking applications. The accelerometer offers smart sleep-to-wake-up (Activity) and return-to-sleep (Inactivity) functions that enable advanced power saving.

The module can be configured to generate interrupt signals by utilising hardware recognition of free-fall events, 6D orientation, tap and double-tap sensing, activity or inactivity, and wake-up events.

The module is compatible with the demands of the leading OSs providing real, virtual, and batch-mode sensors. It has been created to implement in hardware significant motion, relative tilt, timestamp, pedometer functions and offers a high level of customisation. Up to 16 embedded finite state machines can be programmed individually for motion detection or gesture recognition, including hard-fall, absolute wrist tilt, glance, shake, double-shake, or pick-up.

The device also incorporates Machine Learning Core logic, which enables identifying if a data pattern matches a user-defined set of classes. A common example of an application may be activity detection like running, walking, or driving.

The module is provided in a small plastic LGA package, and it is assured to run over an extended temperature range from -40C to +85C. The ultra-small size and weight of the SMD package make it an excellent choice for handheld portable applications such as smartphones, IoT-connected devices, and wearables or any other application where decreased package size and weight are needed.
