These parameters are characterized but not tested.

† 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

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 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 pin. When an external clock input is used, the “max” cycle time 
limit is “DC” (no clock) for all devices.

By design.

Period of the slower clock.

To ensure these voltage tolerances, V

DD

 and V

SS

 must be capacitively decoupled as close to the device as 

possible. 0.1
