Acal BFi: Digital, 3-axis Accelerometer The BMA250 is an advanced, ultra-small, tri-axial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. The BMA250 allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers. Ultra-Small package LGA package (12 pins), footprint 2mm x 2mm, height 0.95mm Digital interface SPI (4-wire, 3-wire), I²C, 2 interrupt pins VDDIO voltage range: 1.2V to 3.6V Programmable functionality Acceleration ranges ±2g/±4g/±8g/±16g Low-pass filter bandwidths 1kHz - <8Hz On-chip interrupt controller Motion-triggered interrupt-signal generation for - new data - any-motion (slope) detection - tap sensing (single tap / double tap) - orientation recognition - flat detection - low-g/high-g detection Stand-alone capability (no microcontroller needed) Ultra-low power ASIC Low current consumption, short wake-up time, Advanced features for system power management RoHS compliant, halogen-free
Number of Axes: 3 Measurement Range (g): ±2, ±4, ±8, ±16 Scale Factor/Sensitivity (LSB/g): 256, 128, 64, 32
Cross axis sensitivity (% typ): 1 Bandwidth (Hz): 8 to 1000 Noise (μg/√Hz): 800 Package: LGA-12 Operating Temperature Range (°C): -40 to 85
