Tri-Axis, 2.5g - 8g, Digital (I²C or SPI), 3x5x0.9mm LGA - KXSS5-3028

The KXSS5 is a high-performance, low-power, digital tri-axis accelerometer with integrated freefall and high-g drop detection algorithms, either of which can flag a drop event. The accelerometer can use either I²C or SPI digital interfaces to communicate with the chip to trigger A/D conversions, set thresholds or threshold delays, or manage power consumption. The KXSS5 is delivered in a 3 x 5 x 0.9 mm, 14-pin, LGA package with an operating temperature range of -40°C to +85°C. The KXSS5 offers a full-scale output range of ±3g and operates from 1.8 V to 3.6 V DC supply.



  • I2C, SPI or Analog output
  • Excellent performance over temperature
  • Embedded algorithms for free-fall and drop detection

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.
