ARM-based Sensor Hub Embeds Accelerometer
Kionix Inc.

The KX23H sensor hub integrates a three-axis accelerometer with a 32-bit ARM Cortex-M0 microcontroller(MCU) in a 3 mm x 3 mm x 0.9 mm package. It 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.

Sensor hub features include:

• Low power : 1µ[email protected]; 2µ[email protected]; 146µ[email protected]
• ±2g, 4g, 8g full scale range
• Data Rate 0.781Hz to 1.6KHz
