Digital, triaxial acceleration sensor General description The BMA180 is an ultra high performance digital triaxial acceleration sensor, aiming for low power consumer market applications. The BMA180 allows high accurate measurement of accelerations in 3 perpendicular axes and thus sen - ses tilt, motion, shock and vibration in cell phones, handhelds, computer peripherals, man-machine inter- faces, virtual reality features and game controllers. BMA180 target applications Navigation (INS / Dead Reckoning) f High accurate tilt detection f (e.g. tilt compensated compass) Pointing and menu scrolling f Display profile switching (portrait / landscape) f Gaming f Drop detection for warranty logging f Shock detection f Step-counting f Sensor operation The BMA180 represents a new generation of digital acceleration sensors with a unique performance and feature set within 3 mm x 3 mm x 0.9 mm standard LGA package. The BMA180 is highly configurable in order to give the designer full flexibility when integrating the sensor into his system. All features can be set by software via the digital interface. Here the user can choose between an I²C and an SPI (4-wire) interface mode. Key features BMA180 All parameters and features user programmable f 7 user programmable g-ranges and 10 selectable f bandwidth settings Low-power consumption f Ultra-low-power self-wake-up mode f User programmable interrupt engine f 0g offset regulation and in-field offset re-calibration f with ultra-high accuracy SPI (4-wire) / I²C interface f RoHS compliant, halogen-free f Technical data BMA180 Sensitivity axes Measurement range (switchable via SPI / I²C) Sensitivity (calibrated) Resolution Nonlinearity Zero-g offset (ex-factory) Zero-g offset (after offset fine tuning) Zero-g offset temperature drift Noise density Bandwidth low pass (switchable high pass via SPI/I²C) band pass Digital input / output Supply VDD voltages VDDIO Current consumption Temperature range x / y / z ±8g, ±16g 1g: 8192LSB/g 1.5g: 5460LSB/g 2g: 4096LSB/g 3g: 2730LSB/g 4g: 2048LSB/g 8g: 1024LSB/g 16g: 512LSB/g 14bit  0.244mg (±2g range) (switchable 12 bit option) ±0.15% FS (±2g range) ±15mg ±5mg ±0.5mg/K 150µg / √Hz 10Hz ... 1200Hz 1Hz 0.2 ... 300Hz SPI & I²C, interrupt pin 650µA -40°C … +85°C

Various motion detection scena- rios can be identified by the BMA180 and signaled to the system via a simple interrupt pin. By using the digital serial interface, the exact details of the motion event that triggered the interrupt can be read-out. Following motion detection use case scenarios are supported by the interrupt engine: Any-motion (slope) detection f Tap sensing f Low-g / high-g detection f Data-ready with sample skipping option f Self-wake-up f The interrupts can be conveniently configured by the user and thus perfectly support the integration of the BMA180 into the user’s system environment. Another important feature of the BMA180 acceleration sensor is the power management module. This module allows for optimizing the sensor’s power consumption in-line with the specific user requirements. Thus, it is not necessary to operate the sensor at full power for all application scenarios all the time. For some use cases the power consumption drastically shrinks to just a fraction of what would be required in full per - formance mode. Moreover this feature of the BMA180 allows for an intelligent system power management and thus significant reduction of the whole system’s power consumption. In particular, this helps increa - sing battery life-time of any kind of mobile device. Pin No. Name Function
