Timing Diagrams and Specifications
Data in the Typical (“Typ”) column is at 5V, +25°C unless otherwise stated. These parameters are for
design guidance only and are not tested.
All specified values are based on characterization data for that particular oscillator type under standard
operating conditions with the device executing code. Exceeding these specified limits may result in an
unstable oscillator operation and/or higher than expected current consumption.
When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.
A duty cycle of no more than 60/40 (High Time / Low Time or Low Time / High Time) is recommended for
external clock inputs.
