Timing Diagrams and Specifications
Data in "Typ" column is at 5V, 25 C unless otherwise stated. These parameters are for design guidance only and are not
tested.
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 the OSC1/CLKIN pin.
When an external clock input is used, the "Max." cycle time limit is "DC" (no clock) for all devices. OSC2 is disconnected
(has no loading) for the PIC12CE67X.
