Current Consumption
Note: At temperatures above 40°C, the above fi gures start to
increase due to leakage. Expect +2μA at 60°C, and +6μA at
80°C.
Note: VBAK current in normal operation mode is dependent
on clock feedthrough from CLK0 & CLK1 to V
case conditions with CLK output at 33MHz and VDD = 5.5 V,
VBAK input current could be up to 2μA. At lower frequencies,
VBAK current drops to approximately 50nA. This effect is relat-
ed to the same phenomenon as described in the V
tion section, and the net feedthrough current on to V
be positive or negative, dependent on V
levels.
