Kionix (Ithaca, NY) announced a new integrated sensor hub device, the KX23H, combining a high-performance, very low power 3-axis accelerometer with a 32-bit ARM Cortex-M0 microcontroller in a single 3x3x0.9mm package. The KX23H also includes a library of advanced motion processing software, providing the user with pedometer and caloric counting algorithms, as well as activity monitoring and the ability to detect differences between states such as Stop/Walk/Run/Car/Train etc. In addition, the KX23H includes embedded algorithms for Tap/Double-Tap, screen rotation, tilt, and other common applications. Other features include:

  • Low power: 1µA@standby; 2µA@3.1Hz; 146µA@1.6kHz.
  • Data rate of 0.781Hz to 1.6KHz.
  • 16-bit resolution.
  • Low noise with FlexSet Performance Optimizer.
  • Embedded 256-byte FIFO/FILO buffer.
  • Internal voltage regulator.
  • Embedded wake-up function.
  • Digital high-pass filter outputs.
  • Integrated directional tap/double-tap and device-orientation algorithms.
  • High shock survivability (10,000g).
