1 / 98 page  FXLS8964AF 3-Axis Low-g Accelerometer Rev. 3.4 — 7 December 2021 Product data sheet 1 General description FXLS8964AF is a compact 3-axis MEMS accelerometer designed for use in automotive remote keyless entry (key fob) applications that require ultra-low-power wake-up on motion. The part supports both high-performance and low-power operating modes, allowing maximum flexibility to meet the resolution and power needs for various use case implementations. A number of advanced, integrated digital features enable designers to reduce the overall system power consumption and simplify host data collection. FXLS8964AF is available in a 2 mm x 2 mm x 0.95 mm 10-pin DFN package with 0.4 mm pitch and wettable flanks. The device is qualified to AEC-Q100 and operates 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 FXLS8964AF an ideal accelerometer for automotive security and convenience applications. 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: 280 µg/√Hz 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 • Selectable ODRs up to 3200 Hz; Flexible Performance mode allows for 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) • Dedicated 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 self-test diagnostic: Device motion or orientation does not impact the result. |
