Dual-Axis SPI Inertial Sensor
MMA68xx, a SafeAssure solution, is a SPI-based, 2-axis, medium-g, over-
damped lateral accelerometer designed for use in automotive airbag systems.
Features
• ±20g to ±120g full-scale range, independently specified for each axis
• 3.3V or 5V single supply operation
• SPI-compatible serial interface
• 10-bit digital signed or unsigned SPI data output
• Independent programmable arming functions for each axis
• Twelve low-pass filter options, ranging from 50 Hz to 1000 Hz
• Optional offset cancellation with > 6s averaging period and < 0.25 LSB/s slew
rate
• Pb-Free 16-Pin QFN-6 by 6 Package
Referenced Documents
• AECQ100, Revision G, dated May 14, 2007 (http://www.aecouncil.com/)
