Acal BFi: Digital, 3-axis Accelerometer

The BMA250E is a tri-axial, low-g acceleration sensor with digital output for consumer application. It allows measurements of acceleration in three perpendicular axes. An evaluation circuitry (ASCI) converts the output of a micromechanical acceleration-sensing structure (MEMS) that works according to the differential capacitance principle.

Package and interfaces of the BMA250E have been defined to much a multitude of hardware requirements. Since the sensor features an ultra-small footprint and a flat package it is ingeniously suited for mobile application.

The BMA250E offers a variable VDDIO voltage range from 1.2V to 3.6V and can be programmed to optimize functionality, performance and power consumption in customer specific application.

In addition it features an on-chip interrupt controller enabling motion-based applications without use of a microcontroller.

The BMA250E senses tilt, motion, inactivity and shock vibration in cell phones, handheld, computer peripherals, man-machine interfaces, virtual reality features and game controllers.
