1 / 100 page  FXLS8971CF 3-Axis Low-g Accelerometer Rev. 2.1 — 7 March 2024 Product data sheet 1 General description FXLS8971CF is a compact 3-axis MEMS accelerometer designed for use in a wide range of industrial and medical IOT applications that require ultra-low-power wake-up on motion as well as good performance over temperature. The part supports both high-performance and low-power operating modes, allowing maximum flexibility to meet the resolution and power needs for various unique use cases. A number of advanced, integrated digital features enable designers to reduce the overall system power consumption and simplify host data collection. FXLS8971CF is available in a 3 mm x 3 mm x 1.25 mm 12-pin QFN package with 0.65 mm pitch and wettable flanks. The device is qualified to industrial standards over the extended –40 °C to +105 °C temperature range. The combination of sensor performance, system power-saving features, and extended over-temperature- range performance makes FXLS8971CF an ideal accelerometer for motion and position sensing in the IOT and industrial segments. 2 Features and benefits • ±2/4/8/16 g user-selectable, full-scale measurement ranges • 12-bit acceleration data • 8-bit temperature sensor data • Low noise: 230 µg/√Hz typical in high performance mode • Low-power capability: – ≤ 1 μA IDD for ODRs up to 6.25 Hz – < 4 µA IDD for ODRs up to 50 Hz • Post-board mount zero-g Offset and TCO performance of ±30 mg (typ) and ±0.15 mg/°C (typ), respectively • Selectable ODRs from 0.78 to 3200 Hz in both low power and high performance modes • Flexible performance mode allowing custom ODRs with programmable decimation (resolution) and idle-time settings • 144 byte output data buffer (FIFO/LIFO) capable of storing up to 32 12-bit X/Y/Z data triplets • Flexible Sensor Data Change Detection (SDCD) function for realizing motion or no motion, high-g/low-g, freefall, and other inertial events • Autonomous orientation detection function (Portrait/Landscape/Up/Down) • Self-governed low-power motion-detection mode with one wire interface option • 12-bit vector magnitude calculation • Trigger input for synchronizing data collection with an external system • I2C interface frequencies up to 1 MHz; 3- and 4-wire SPI interface with clock frequencies up to 4 MHz • Bidirectional, robust self-test diagnostic: Device motion or orientation does not impact the result. |
