LSM6DSO iNEMO™ Inertial Measurement Unit (IMU)

STMicroelectronics' LSM6DSO is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope boosting performance at 0.55 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer. The LSMDSOX contains a machine learning core.

The LSM6DSO supports main OS requirements, offering real virtual and batch sensors with 9 kbytes for dynamic data batching. The STMicroelectronics family of MEMS sensor modules leverage the robust and mature manufacturing processes already used to produce 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 LSM6DSO has a full-scale acceleration range of ±2 g, ±4 g, ±8 g, and ±16 g and an angular rate range of ±125 dps, ±250 dps, ±500 dps, ±1000 dps, and ±2000 dps. The LSM6DSO fully supports EIS and OIS applications as the module includes a dedicated configurable signal processing path for OIS and auxiliary SPI, configurable for both the gyroscope and accelerometer.

High robustness to mechanical shock makes the LSM6DSO the preferred choice of system designers for the creation and manufacturing of reliable products. The LSM6DSO is available in a plastic land grid array (LGA) package.
