Supply Current of IO modules
Power-down Supply Current
Atmel ATtiny24/44/84 [Preliminary]
The tables and formulas below can be used to calculate the additional current consumption for
the different I/O modules in Active and Idle mode. The enabling or disabling of the I/O modules
are controlled by the Power Reduction Register. See
for details.
