† Notice:

Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

All input pins have an

internal pull-up

Note 1:

VDD pins should be filtered with a 0.1 µF capacitor connected between VDD and VSS.

The addition of IDDCORE and IDDIO provides the total current consumption of the device.

tSU is time to 100 ppm stable output frequency after VDD is applied and outputs are enabled.

See the Output Waveform section for more information.
