Self-crowned as the market’s smallest three axis MEMS accelerometer, the BMA355 sports a wafer-level chip scale package size of 1.2 mm x 1.5 mm x 0.8 mm3. With a current consumption of 130 µA, the device is highly suitable for use in wearable devices. It features an enhanced intelligent interrupt engine. Multiple motion detection scenarios are identifiable and signaled to the host system via two configurable interrupt pins. Interrupts indicate data-ready for processor synchronization, any-motion (slope) detection for wake-up, tap sensing for tap-sensitive user interface (UI) control, orientation change recognition for portrait or landscape switching, flat detection for position sensitive switching, low-g / high-g detection for shock and free-fall detection, or no-motion for power saving. Interrupt parameters are configurable. For more details and specs, go to
