There are several possibilities to consider when trying to minimize the power consumption in
an AVR controlled system. In general, sleep modes should be used as much as possible, and
the sleep mode should be selected so that as few as possible of the device’s functions are
operating. All functions not needed should be disabled. In particular, the following modules
may need special consideration when trying to achieve the lowest possible power
consumption.
If enabled, the ADC will be enabled in all sleep modes. To save power, the ADC should be dis-
abled before entering any sleep mode. When the ADC is turned off and on again, the next
conversion will be an extended conversion. Refer to
verter” on page 191
When entering Idle mode, the Analog Comparator should be disabled if not used. When enter-
ing ADC Noise Reduction mode, the Analog Comparator should be disabled. In other sleep
modes, the Analog Comparator is automatically disabled. However, if the Analog Comparator
is set up to use the Internal Voltage Reference as input, the Analog Comparator should be dis-
abled in all sleep modes. Otherwise, the Internal Voltage Reference will be enabled,
independent of sleep mode. Refer to
211
If the Brown-out Detector is not needed by the application, this module should be turned off. If
the Brown-out Detector is enabled by the BODLEVEL Fuses, it will be enabled in all sleep
modes, and hence, always consume power. In the deeper sleep modes, this will contribute
significantly to the total current consumption. Refer to
page 51
The Internal Voltage Reference will be enabled when needed by the Brown-out Detection, the
Analog Comparator or the ADC. If these modules are disabled as described in the sections
above, the internal voltage reference will be disabled and it will not be consuming power.
When turned on again, the user must allow the reference to start up before the output is used.
If the reference is kept on in sleep mode, the output can be used immediately. Refer to
6.2 “Internal Voltage Reference” on page 53
Output the internal voltage reference is not needed in the deeper sleep modes. This module
should be turned off to reduce significantly to the total current consumption. Refer to
