Features

Energy Efficiency Quick Facts

  • Combination of the accelerometer with the low-power CPU to perform pre-processing of the data without requiring the intervention of a more powerful processor
  • Intelligent processing of data can be done more efficiently on MMA955xL than on the host processor
  • Slow internal clock to reduce power in idle mode to 20 µA typical
  • Programmability allows you to specify conditions before notifying the main processor
  • Software configurable FIFOs allow local storage data reducing number of interactions for main processor
