What Defines Low Power?

over RUN Mode
Of Note
Run ON ON ON ON ON 0 Full current consumption.
DozeSlower Clock Rate
Slower Clock Rate
ON ON ON 25-65% CPU is slowed down to as much as 1/128 of its Run mode speed.
Idle OFF OFF ON ON ON 0,7 Use in moments when code execution is not needed
Sleep OFF OFFOFF - Except for peripherals with their own clock
ON ON 70% - 85%RAM and registers maintained. Latencies of up to tens of microseconds are expected.
Low Voltage Sleep
OFF OFFOFF - Except for peripherals with their own clock
Low Voltage Enabled ON 0,9 For longer-term sleep than Sleep,
when longer latencies are acceptable.
Deep Sleep OFF OFF OFF OFF OFF 97%+
Most of the MCU is OFF except for maybe a timer, interrupt handling, and a Real Time Clock and Calendar.
