Note 1: Performance is guaranteed only under the conditions listed in this Table and is not guaranteed over the full operating or storage temperature ranges. Operation at elevated
temperatures may reduce reliability of the device.
Note 2: A 5 V charge pump power supply (on pin 10 and/or pin 19) results in higher power-down leakage current.
Note 3: The minimum synthesizer frequency is 12 x FOSC, where FOSC is the frequency at the Xtalin/OSC pin.
