AC CHARACTERISTICS: PIC16F630/676 (INDUSTRIAL, EXTENDED)
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 OSC1 pin. When an external clock input is used, the ‘max’ cycle time limit is ‘DC’ (no clock)
for all devices.
These parameters are characterized but not tested.
