Selectable \u00b12g\/\u00b14g\/\u00b18g measurement ranges with data rates from 1.56 Hz to 800 Hz suit various motion sensing applications. The embedded 32-sample FIFO reduces bus traffic and MCU overhead. Two programmable interrupt pins support freefall, motion, and transient detection. Ultra-low 6 \u00b5A standby current preserves battery life.","working_principle":"The FXLS8471Q uses capacitive MEMS sensing elements to detect acceleration along three orthogonal axes. The MEMS capacitance changes are converted to digital values by 14-bit ADCs. A digital filter engine applies configurable low-pass filtering. The FIFO buffer stores up to 32 samples, reducing MCU polling overhead. Interrupt engines compare acceleration against programmable thresholds for autonomous event detection.","pin_description":"
