The KXSC7 from Kionix Inc., Ithaca, NY, is 3 by 3 by 0.9 mm, draws 230 µA, includes a factory programmable low-pass filter, and has a ±1.5 to ±10 g measurement range. The device features inertial wake up with interrupt, sampling at low frequency and awaiting an acceleration event on any axis that exceeds the motion-interrupt threshold. The event triggers the accelerometer to return to its normal operational mode. The internal low-pass filter provides programmable signal processing. The sensor can be factory programmed for sensitivity between 1.5 and 10 g and supply voltages between 1.8 and 5.0 V.
