Table 29-10. ATmega3250A: Additional Current Consumption (percentage) in Active and Idle
It is possible to calculate the typical current consumption based on the numbers from
10
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI
enabled at V
add 13.1% for the USART0, 13.0% for the SPI, and 13.2% for the TIMER1 module. Reading
from
F = 1MHz. The total current consumption in idle mode with USART0, TIMER1, and SPI enabled,
gives:
