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.

Note 1: Instruction cycle period (T

CY

) 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 consumption. All devices are tested to operate at “min” values with an external 
clock applied to the OSC1 pin. When an external clock input is used, the “max” cycle time limit is “DC” (no 
clock) for all devices.

2: By design.
3: Period of the slower clock.
4: To ensure these voltage tolerances, V

DD

 and V

SS

 must be capacitively decoupled as close to the device as 

possible. 0.1

μF and 0.01 μF values in parallel are recommended.
