KXTI9-1001
Tri-Axis, User Selectable 2g, 4g, 8g, Digital (I²C) Output, 3x3x0.9mm LGA - KXTI9-1001

The Kionix KXTI9 is a low power, high performance tri-axis accelerometer with digital I²C output. The KXTI9 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 and provides a triggered low resolution or high resolution mode.
Pin and register compatible with Kionix’ popular KXTF9, the KXTI9 features enhanced embedded Screen Rotation, Directional Tap/Double Tap, Orientation Detection and Low Power Motion Interrupt.
The KXTI9 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.

Not Recommended for New Designs.

IoT Evaluation and Development Kit Cart Kionix's IoT evaluation kit utilizes hardware platform based on Nordic Semiconductor's Bluetooth LE SoC. The compact (27/32mm x 4.2mm), highly integrated modular sensor system integrates Kionix's accelerometer (KX122-1037), combo accel-mag (KMX62-1031), and combo accel-gyro (KXG07) sensors along with ROHM's barometric pressure sensor (BM1383AGLV). Additional sensors can be evaluated using the add-on board that can fit inside the kit. This enables measurement of 3D acceleration, 3D magnetism, 3D rotation, air pressure, and temperature, making it ideal for training, prototyping, and initial set development of IoT and wearable applications.
