STMicroelectronics ISM330IS MEMS module

The ISM330IS is a 6-axis IMU (inertial measurement unit) system-in-package featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, boosting performance at 0.59 mA in high-performance mode and enabling always-on low-power features for optimal motion results in industrial and IoT solutions. The ISM330IS has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±250/±500/±1000/±2000 dps. The ISM330IS features programmable interrupts and an on-chip sensor hub, which includes up to six sensors: the internal accelerometer & gyroscope and four external sensors. The ISM330IS embeds a new ST category of processing, ISPU (intelligent sensor processing unit) to support real-time applications that rely on sensor data. The ISPU is an ultralow-power, high-performance programmable core, which can execute signal processing and AI algorithms in the edge. The main benefits of the ISPU are C programming and an enhanced ecosystem with libraries and 3rd party tools/IDE. Its optimized ultralow-power hardware circuitry for real-time execution of the algorithms is a state-of-the-art feature for any wireless sensor node from small equipment or accessories to enterprise solutions for Industry 5.0 (for example, anomaly detection, asset tracking, factory automation, and so forth). The part number ISM330ISN, moreover, can execute the machine learning libraries generated by ST's NanoEdge AI Studio, a powerful tool that allows anyone to easily create machine learning libraries with on-sensor learning. The ISM330IS and ISM330ISN are available in a plastic, land grid array (LGA) package.
