Note 1:

These parameters are characterized but not tested.

Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not

tested.

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 con-

sumption. All devices are tested to operate at “min” values with an external clock applied to OSC1 pin. When an external

clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.
