Table 52.
Additional Current Consumption (percentage) in Active and Idle mode (Continued)
It is possible to calculate the typical current consumption based on the numbers from Table 51
for other V
Calculate the expected current consumption in idle mode with USART0 and TIMER1 enabled at
V
USART0, and 11% for the TIMER1 module. Reading from Figure XXXX, we find that the idle
current consumption is ~0,075mA at V
idle mode with USART0 and TIMER1 enabled, gives:
Same conditions as in example 1, but in active mode instead. From Table 52 second column we
see that we need to add 3.3% for the USART0, and 2.0% for the TIMER1 module. Reading from
Figure XXXX, we find that the active current consumption is ~0,42mA at V
1MHz. The total current consumption in idle mode with USART0 and TIMER1 enabled, gives:
All I/O modules should be enabled. Calculate the expected current consumption in active mode
at V
to be ~ 4.0mA (from Figure XXXX). Then, by using the numbers from Table 52 - second column,
we find the total current consumption:
