BMA253中文资料Digital, triaxial acceleration sensor数据手册Bosch规格书

描述 Description

The BMA253 is a triaxial, low-g acceleration sensor with digital output for consumer 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 interfaces of the BMA253 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 BMA253 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 applications. In addition it features an on-chip interrupt controller enabling motion-based applications without use of a microcontroller.

应用 Application

- Display profile switching (portrait/landscape, face-up/face-down switching)
- Flat detection
- Tap / double tap sensing
- Menu scrolling
- Gaming
- Advanced power management for mobile devices
- Shock and free-fall detection
- Step-counting
- Tilt compensation for electronic compass
