Power-down Supply Current
ATmega325P/3250P
Example
It is possible to calculate the typical current consumption based on the numbers from
for other V
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI
enabled at V
USART0, 5.9% for the SPI, and 2.6% for the TIMER1 module. From
the idle current consumption is ~0.21mA at V
sumption in idle mode with USART0, TIMER1, and SPI enabled, gives:
