* These parameters are characterized but not tested.

† Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1: Instruction cycle period (TCY) 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/CLKIN pin.

When an external clock input is used, the "Max." cycle time limit is "DC" (no clock) for all devices.
