* These parameters are characterized but not tested.
† Data in “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
Note 1: Instruction cycle period (T
CY) equals four times the input oscillator time base period. 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. All devices are tested to operate at “min” values with an external clock applied to the OSC1 pin.
When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.
2: To ensure these oscillator frequency tolerances, V
DD and VSS must be capacitively decoupled as close to the device as
possible. 0.1 μF and 0.01 μF values in parallel are recommended.
3: By design.
