Product overview
Description
The ST1VAFE6AX is a biosensor embedding a vAFE channel to detect biopotential signals and a 6-axis IMU featuring a high-performance 3-axis digital accelerometer and 3-axis digital gyroscope for motion tracking.
The device embeds advanced dedicated features and data processing for motion processing like the finite state machine (FSM), sensor fusion low power (SFLP), adaptive self-configuration (ASC), and machine learning core (MLC) with exportable AI features/filters.
The ST1VAFE6AX is available in a small plastic, land grid array (LGA) package of 2.5 x 3.0 x 0.71 mm to address ultracompact solutions.
