ARM-based Sensor Hub Embeds Accelerometer
March 31, 2014
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 : 1µA@standby; 2µA@3.1Hz; 146µA@1.6kHz
The KX23H MCU features:
• ARM Cortex™-M0 32MHz
