1. Timer_A is clocked by f_(DCOCLK) = f_(DCO) = 1 MHz. All inputs are tied to 0 V or to V_CC. Outputs do not source or sink any current.
2. All inputs are tied to 0 V or to V_CC. Outputs do not source or sink any current.
3. The LPM3 currents are characterized with a Micro Crystal CC4V−T1A (9pF) crystal and OSCCAPx=01h.
4. Current for brownout included.
Current consumption of active mode versus system frequency
I_(AM) = I_(AM) [1 MHz] × f_(System) [MHz]
Current consumption of active mode versus supply voltage
I_(AM) = I_{(AM) [3 V]} + 175 μA/V × (V_CC – 3 V)
