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 exe-
cuting 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. OSC2 is discon-
nected (has no loading) for the PIC12C67X.
