Figure 29. Typical RC Oscillator Frequency as a Function of the External Capacitance
with a 45 k Resistor
Caution: When using the external RC oscillator mode, the oscillator can stop oscillating if the
power supply drops below 2.7 V, but before the power supply drops to the Voltage Brown-
Out threshold. The oscillator resumes oscillation when the supply voltage exceeds 2.7 V.
