KX132-1211
TRI-AXIS 16-BIT ACCELEROMETERS SUPPORTING RANGES FROM ±2G TO ±16G, DIGITAL (I²C/SPI) OUTPUT, ADVANCED DATA PATH, ADVANCED WAKE-UP/BACK-TO-SLEEP ENGINE, FIFO BUFFER, -40°C TO +105°C OPERATING TEMPERATURE RANGE, EMBEDDED TEMPERATURE SENSOR IN A 2X2X0.9MM LGA 12-PIN - KX132-1211

The KX132-1211 is a tri-axis ±2g, ±4g, ±8g, ±16g silicon micromachined accelerometer featuring a user-configurable 3 stage Advanced Data Path (ADP) consisting of a low-pass filter, low-pass/high-pass filter, and RMS calculation engine. The new KX132-1211 accelerometers also feature advanced Wake-Up and Back-to-Sleep detection with a high-resolution threshold capability configurable down to 3.9mg, embedded temperature sensor, 512-byte buffer that continues to record data even when being read, and embedded engines for orientation, Directional-TapTM/Double-TapTM, and Free fall detection. The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress. The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device wafer. A separate ASIC device packaged with the sense element provides signal conditioning and intelligent user-programmable application algorithms. The new KX132-1211 accelerometers offer lower noise and improved linearity over of the entire temperature range. The accelerometer is delivered in a 2 x 2 x 0.9 mm LGA 12-pin plastic package operating from a 1.7V – 3.6V (VDD) / 1.2V-3.6V (IO_VDD) DC supplies. Internal voltage regulators are used to maintain constant internal operating voltages over the range of input supply voltages. This results in stable operating characteristics even if the supply voltage changes. I²C or SPI digital protocol is supported to configure the chip, read acceleration outputs, and check for updates to the orientation, Directional-TapTM/Double-TapTM detection, Free fall detection, and activity monitoring algorithms. Two configurable interrupt pins are also available to show the output of the embedded detection algorithms.

RoKiX IoT Platform Cart The RoKiX IoT Platform provides a powerful and easy to use environment to begin the evaluation of ROHM and Kionix products. Multiple hardware options are supported (RoKiX IoT Platform HW), as well as common, hardware independent SW tools (RoKiX IoT Platform SW). RoKiX Windows GUI consists of an easy to use graphical user interface for displaying and recording sensor data, and a register map editor which allows the user to see and change the content of control registers. RoKiX Python CLI, in turn, provides reference implementation for driver SW and also a convenient way to access sensor low level features and versatile data logging functionality. Finally, RoKiX Android App provides an easy way to display and log the sensor data from a RoKiX Sensor Node over Bluetooth.
