The Freescale Semiconductor MMA8451QT is a versatile 3-axis digital accelerometer designed for low-power applications. It offers 14-bit resolution and dynamically selectable full-scale ranges of ±2g, ±4g, or ±8g.
This capacitive, micromachined accelerometer is equipped with embedded functions that can reduce host processor load, such as motion detection, freefall detection, pulse detection, and orientation detection. It communicates via an I2C interface, supporting clock speeds up to 2.25 MHz.
The MMA8451QT operates with a supply voltage range of 1.95V to 3.6V and an interface voltage range of 1.6V to 3.6V. Its compact 3 mm by 3 mm by 1 mm QFN package makes it suitable for space-constrained designs. The device also includes a 32-sample FIFO buffer and configurable interrupt pins.
Typical applications include e-compass systems, orientation detection for portable devices like notebooks and e-readers, real-time activity analysis such as pedometer step counting, and motion detection for power saving in mobile products.
