Table 181.
Additional Current Consumption for the different I/O modules (absolute values)
Table 182.
Additional Current Consumption (percentage) in Active and Idle mode
It is possible to calculate the typical current consumption based on the numbers from
Table 181 for other V
Calculate the expected current consumption in idle mode with USART0, TIMER1, and
TWI enabled at V
we see that we need to add 17% for the USART0, 24% for the TWI, and 10% for the
TIMER1 module. Reading from Figure 172 on page 393, we find that the idle current
consumption is ~0,15mA at V
idle mode with USART0, TIMER1, and TWI enabled, gives:
