It is possible to calculate the typical current consumption based on the numbers from Table 2 for
other V
Calculate the expected current consumption in idle mode with USART0, TIMER1, and TWI
enabled at V
18% for the USART0, 26% for the TWI, and 11% for the TIMER1 module. Reading from Figure
3, we find that the idle current consumption is ~0,075 mA at V
current consumption in idle mode with USART0, TIMER1, and TWI enabled, gives:
Same conditions as in example 1, but in active mode instead. From Table 2, second column we
see that we need to add 3.3% for the USART0, 4.8% for the TWI, and 2.0% for the TIMER1
module. Reading from Figure 1, we find that the active current consumption is ~0,42 mA at V
= 3.0V and F = 1 MHz. The total current consumption in idle mode with USART0, TIMER1, and
TWI enabled, gives:
All I/O modules should be enabled. Calculate the expected current consumption in active mode
at V
to be ~ 4.0 mA (from Figure 2). Then, by using the numbers from Table 2 - second column, we
find the total current consumption:
