The KXTIK features user- selectable parameters including 8-bit or 12-bit modes, g-ranges from 2g, 4g or 8g, and Output Data Rates from 12.5 Hz to 800 Hz. A 252 byte FIFO/FILO buffer offers programmable watermark interrupt and provides a triggered low resolution or high resolution mode. The KXTIK features a 16-pin package, making it pin compatible with popular products on the market. The KXTIK also offers enhanced embedded Screen Rotation, Directional Tap/Double Tap, Orientation Detection and Low Power Motion Interrupt. The KXTIK has an internal voltage regulator that allows operation from 1.8 V to 3.6 V with an operating temperature range of -40C to +85C. KXTIK Accelerometer 3x3x0.9mm Accelerometer with FIFO/FILO Buffer The performance parameters below are programmed and tested at 2.6 volts and T = 25C. The device can accept supply voltages from 1.8V to 3.6V. Due to internal voltage regulators, there should be minimal change with supply voltage variations.
