NOTES:

1. Timer_B is clocked by f(DCOCLK) = f(DCO) = 1 MHz. All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current.

2. All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current.

3. All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current. The current consumption in LPM3 is measured with

active Basic Timer1 and LCD (ACLK selected). The current consumption of the Comparator_A and the SVS module are specified

in the respective sections. The LPM3 currents are characterized with a KDS Daishinku DT−38 (6 pF) crystal and OSCCAPx=1h.

4. Current consumption 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 × (VCC – 3 V)
