tailieunhanh - MMA8452Q, 3-Axis, 12-bit/8-bit Digital Accelerometer

The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 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. | Freescale Semiconductor Data Sheet Technical Data An Energy Efficient Solution by Freescale Document Number MMA8452Q Rev. 06 2015 VRoHS MMA8452Q MMA8452Q 3-Axis 12-bit 8-bit Digital Accelerometer The MMA8452Q is a smart low-power three-axis capacitive micromachined accelerometer with 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 MMA8452Q has user selectable full scales of 2g 4g 8g with high-pass filter filtered data as well as non-filtered data available real-time. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing the MMA8452Q to monitor events and remain in a low power mode during periods of inactivity The MMA8452Q is available in a 3 mm x 3 mm x 1 mm QFN package.
