Power-down Supply Current
Example 1
Table 29-2.
It is possible to calculate the typical current consumption based on the numbers from
on page 343
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI
enabled at V
that we need to add 12.4% for the USART0, 10.8% for the SPI, and 18.6% for the TIMER1 mod-
ule. Reading from
mA at V
TIMER1, and SPI enabled, gives:
