Accelerometer features dual user-programmable state machines

September 12, 2012 // By Julien Happich
Kionix's KXCNL configurable accelerometer features two state machines that allow designers to dynamically program the device for numerous applications, enabling the device to simultaneously run multiple applications at the chip level.

This takes significant processing load off the system's main applications processor and conserving power. The KXCNL enables a wide combination of applications from basic screen rotation to more sophisticated programs such as freefall detection, pedometry, Tap/Double-Tap, power management and more. The KXCNL allows applications to be swapped out "on the fly," providing designers with a new level of flexibility and extensibility. To assist customers in adapting to this new flexibility, Kionix is providing a library of pre-written state programs, while still allowing customers to write their own state programs if they choose.

The 3x3x0.9mm accelerometer features user-selectable 2g, 4g, 6g, and 8g ranges, a user-programmable ODR. It draws only 2 to 250µA in operation from a 1.7 to 3.6V operating voltage.
