Features

Power-Saving Features

  • Two ultra-low-power stop modes, one of which allows limited use of peripherals
  • New low-power run and wait modes
  • 6 µs typical wake up time from stop mode
  • Internal clock Source (ICS)—module containing a frequency locked-loop (FLL) controlled by internal or external reference
  • Oscillator (OSC)—loop-control Pierce oscillator
    • crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
  • Clock gating disables clocks to unused peripherals
