General Description
The BMA220 is a triaxial, low-g acceleration sensor with digital output for consumer market
applications. It allows measurements of acceleration in three perpendicular axes. An evaluation
circuitry (ASIC) converts the output of a micromechanical acceleration-sensing structure
(MEMS) that works according to the differential capacitance principle.
Package and interface have been defined to match a multitude of hardware requirements. Since
the sensor features an ultra-small footprint and a flat package it is ingeniously suited for mobile
applications. The sensor offers a variable I/O supply voltage range from 1.6V to 3.6V and can
be programmed to optimize functionality, performance and power consumption in customer
specific applications. In addition it features an on-chip interrupt controller enabling motion-based
applications without use of a microcontroller.
The BMA220 senses tilt, motion and shock vibration in cell phones, handhelds, computer
peripherals, man-machine interfaces, virtual reality features and game controllers.
