Tables and formulas below can be used to calculate additional current consumption for the different I/O modules in Active and Idle mode. Enabling and disabling of I/O modules is controlled by the Power Reduction Register. See Power Reduction Register for details.
| PRR bit | Typical numbers | ||
|---|---|---|---|
| VCC = 2V, f = 1MHz | VCC = 3V, f = 4MHz | VCC = 5V, f = 8MHz | |
| PRTIM0 | 6.6 uA | 40.0 uA | 153.0 uA |
| PRADC (1) | 29.6 uA | 88.3 uA | 333.3 uA |
Note: 1. The ADC is available in ATtiny5/10, only
The table below can be used for calculating typical current consumption for other supply voltages and frequencies than those mentioned in the table above.
| PRR bit | Current consumption additional to active mode with external clock (see Figure 17-1 and Figure 17-2) | Current consumption additional to idle mode with external clock (see Figure 17-7 and Figure 17-8) |
|---|---|---|
| PRTIM0 | 2.3 % | 10.4 % |
| PRADC (1) | 6.7 % | 28.8 % |
