Description:

The ISM330DHCX is a system-in-package featuring a high-performance 3D digital accelerometer and a 3D digital gyroscope tailored for Industry 4.0 applications. ST's MEMS sensor module series leverages robust and mature 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, allowing the design of dedicated circuits which are trimmed to better match the sensing element characteristics.

In the ISM330DHCX, the sensing elements for both the accelerometer and the gyroscope are implemented on the same die, thus guaranteeing superior stability and robustness. The ISM330DHCX features full-scale acceleration ranges of ±2/±4/±8/±16 g and angular rate ranges of ±125/±250/±500/±1000/±2000/±4000 dps, making it suitable for a wide variety of applications. Every design and calibration aspect of the ISM330DHCX has been optimized to achieve very high accuracy, stability, extremely low noise, and complete data synchronization. An unprecedented set of embedded features (Machine Learning Core, programmable FSM, FIFO, Sensor Hub, event decoding, and interrupts) enables the implementation of smart and complex sensor nodes that deliver high performance at very low power. The ISM330DHCX is available in a 14-lead plastic land grid array (LGA) package.
