* These parameters are characterized but not tested.

† 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.

Note 1: All specified values are based on characterization data for that particular oscillator type under standard oper-

ating 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.

2: Instruction cycle period (TCY) equals four times the input oscillator time base period.
