With selectable full-scale ranges of \u00b12 g to \u00b116 g and 12-bit resolution, it delivers accurate acceleration measurements across diverse sensing scenarios. The device consumes just 1 \u00b5A in active mode at 6.25 Hz, dropping to 650 nA in standby and 50 nA in hibernate mode, making it ideal for battery-powered systems. The integrated SDCD block enables autonomous detection of motion, no-motion, freefall, and vector magnitude changes without MCU intervention. A 32-sample FIFO\/LIFO buffer reduces host MCU read frequency, further saving system power. The device supports both I2C (up to 1 MHz) and SPI (up to 4 MHz) interfaces for flexible integration. Note: This product is EOL; NXP recommends the pin\/software-compatible FXLS8964AF\/67AF for automotive or FXLS8974CF for industrial new designs.","working_principle":"The FXLS8962AFR1 uses a capacitive MEMS sensing element to detect acceleration. A proof mass suspended by silicon springs moves relative to fixed electrodes when subjected to acceleration, changing the capacitance between the moving and fixed plates. An ASIC converts these capacitance changes into a digital signal through a sigma-delta ADC, applies digital filtering, and outputs the result via I2C or SPI. The SDCD (Sensor Data Change Detection) block operates autonomously: it compares acceleration data against configurable thresholds to detect events such as freefall (acceleration below threshold on all axes), motion (deviation from reference), and no-motion (stability over a time window). When an event is detected, an interrupt is generated to wake the host MCU. The auto-wake\/sleep mechanism automatically transitions between active and low-power modes based on the SDCD detection, enabling always-on sensing at microampere current levels. The FIFO\/LIFO buffer stores up to 32 samples, allowing the MCU to read data in bursts rather than per-sample, reducing bus traffic and MCU wake-up frequency.","pin_description":"
