Freescale Semiconductor Technical Data An Energy Efficient Solution by Freescale MMA8450Q Rev 2, 03/2010 www.DataSheet4U.com 3-Axis, 8-bit/12-bit Digital Accelerometer The MMA8450Q is a smart low-power, three-axis, capacitive micromachined accelerometer featuring 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. The MMA8450Q’s Embedded FIFO buffer can be configured to log up to 32 samples of X,Y and Z-axis 12-bit (or 8-bit for faster download) data.
