Signals and Start-up Time
1006F–AVR–06/07
ATtiny12 features an internal voltage reference with a nominal voltage of 1.22V. This
reference is used for Brown-out Detection, and it can be used as an input to the Analog
Comparator.
The voltage reference has a start-up time that may influence the way it should be used.
The maximum start-up time is 10µs. To save power, the reference is not always turned
on. The reference is on during the following situations:
1. When BOD is enabled (by programming the BODEN fuse)
2. When the bandgap reference is connected to the Analog Comparator (by setting
Thus, when BOD is not enabled, after setting the AINBG bit, the user must always allow
the reference to start up before the output from the Analog Comparator is used. The
bandgap reference uses approximately 10 µA, and to reduce power consumption in
Power-down mode, the user can turn off the reference when entering this mode.
