Description

IIS2DULPXTR is an intelligent digital triaxial linear accelerometer. Its MEMS and ASIC are specifically designed for industrial applications, combining extremely low supply current with multiple advanced features, including normally open anti-aliasing filtering, finite state machine (FSM), and a machine learning core (MLC) with adaptive self-configuration (ASC). And analog hub /Qvar sensing channels.

FSM and MLC with ASC provide excellent edge processing capabilities that are always available for IIS2DULPXTR, while the analog hub /Qvar sensing channel defines a new height of system optimization. The complete set of functions implemented by IIS2DULPXTR's MIPI I3C® target interface and embedded 128-level FIFO buffer makes it a benchmark for system integration in terms of bill of materials, processing power and power consumption.

The IIS2DULPXTR accelerometer offers user-selectable ranges of ±2g/±4g/±8g/±16g and can measure acceleration at output data rates ranging from 1.6Hz to 800Hz.

The IIS2DULPXTR features a dedicated internal engine for handling motion and acceleration detection, including free fall, wake, single/double/triple hit recognition, activity/rest, and 6D/4D direction recognition.

The IIS2DULPXTR adopts a thin and small plastic pad grid array (LGA) package, ensuring normal operation within a wider temperature range (-40 °C to +105 °C).
