It features SDCD for freefall\/motion\/no-motion detection, autonomous orientation detection, 144-byte FIFO\/LIFO, vector magnitude calculation, and bidirectional self-test. The dedicated motion-detection mode with single-wire interface enables ultra-low-power car alarm and T-Box wake-up applications. Available in DFN-10 (2x2mm) with wettable flanks for automotive optical inspection. Product now transitioned to STMicroelectronics.","working_principle":"The FXLS8967AFR3 uses a capacitive MEMS sensing element with a proof mass suspended by silicon springs. Acceleration displaces the proof mass, changing the capacitance between the mass and fixed electrodes. The capacitance change is converted to voltage by a C-V converter, then digitized by a 12-bit ADC. The digital backend provides configurable ODR, filtering, and data processing. In high-performance mode, the full 12-bit resolution and 230\u03bcg\/\u221aHz noise are available. In low-power mode, the ADC duty-cycles to reduce current while maintaining selected ODR. The SDCD (Sensor Data Change Detection) block compares acceleration data against programmable thresholds autonomously, generating interrupts for freefall, motion, or high-g events without MCU intervention. The motion-detection mode uses an ultra-low-power comparator path that can wake the device from hibernate (15nA) on vibration, with a single-wire output to the MCU. The FIFO\/LIFO buffer accumulates up to 32 XYZ samples, allowing the MCU to remain in sleep for extended periods between batch reads.","pin_description":"
