PRODUCT OVERVIEW
The Kionix KXTIA is a low power, high performance tri-axis
accelerometer with digital SPI output. The KXTIA features user
selectable parameters including 8 or 12 bit modes, g-ranges
from +- 2, 4 or 8g, and Output Data Rates from 12.5 Hz to 800
Hz. A 252 byte FIFO/FILO buffer offers programmable
watermark interrupt.
The KXTIA features enhanced embedded Screen Rotation,
Directional Tap/Double Tap, Orientation detection and Low
Power Motion Interrupt. The KXTIA has internal voltage
regulators that allow operation from 1.8 V to 3.6 V and is
delivered in a 3 x 3 x 0.9 mm, 10-pin, LGA package with an
operating temperature range of -40°C to +85°C.

3x3x0.9mm Accelerometer with FIFO/FILO Buffer
The performance parameters below are programmed and tested at 2.6 volts and T = 25°C. 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.
