Specifications

Figure 5-1. Frequency vs Supply Voltage

(1)

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

(2)

Timer_B is clocked by f(ACLK) = 32768 Hz. All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current. The current

consumption in LPM2 and LPM3 are measured with ACLK selected.
