31.1.3.1 Example 1
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI enabled at V
CC
= 3.0V
and F = 1MHz. From Table 31-2, second column, we see that we need to add 13.1% for the USART0, 13.0% for
the SPI, and 13.2% for the TIMER1 module. Reading from Figure 31-6, we find that the idle current consumption is
~0.09 mA at V
CC
= 3.0V and F = 1MHz. The total current consumption in idle mode with USART0, TIMER1, and
SPI enabled, gives:
