† Data in “Typ” column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Instruction cycle period (T
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 oper-
ation and/or higher than expected current consumption. All devices are tested to operate at “min.” values
with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the “max.”
cycle time limit is “DC” (no clock) for all devices.
