FXLS8964AF Datasheet | NXP Semiconductors

3-Axis Low-g Accelerometer Rev. 3.4 - 7 December 2021 Product data sheet 1 General description FXLS8964AF is a pact 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 bination 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...
