Energy Efficiency Quick Facts

  • Targeting extended battery life applications in consumer, industrial and personal health care markets, the QExx family is one of our lowest power microcontroller families and the basis for other derivative low-power devices in the portfolio.
    • Exact pin for pin compatibility, equivalent stop current for 8-bit and 32-bit architectures in the Flexis series of microcontrollers
      • Advanced options to optimize power consumption vs. performance for specific applications
    • Advanced low-power run (up to 32 kHz) and low-power wait modes for S08 and ColdFire microcontroller products
      • ColdFire microcontroller Stop mode emulates S08 Wait mode
    • Ecosystem: CodeWarrior tool suite for Flexis series of microcontrollers provides easy migration between devices to choose power/performance targets
