Energy Efficient Solutions Quick Facts
- 6us wake up time allows an application to wake up, perform task, and quickly go back to sleep, thus saving power.
- CPU and peripherals can run with the voltage regulator in low power mode to allow full functionality at reduced frequency for lower power operation.
- User-selectable peripheral clock gating saves power in run and wait modes.
- Ultra low power real-time counter can be used with low power oscillator, internal or external clock sources in run, wait and stop modes.
