Data Sheet
ADuC7122
56B
POWER CONTROL SYSTEM
A choice of operating modes is available on the ADuC7122.
Table 68 describes which blocks of the ADuC7122 are powered
on in the different modes and indicates the power-up time.
Table 69 gives some typical values of the total current
consumption (analog and digital supply currents) in the different
modes, depending on the clock divider bits when the ADC is
turned off. Note that these values also include current consumption
of the regulator and other parts on the test board on which these
values were measured.
