Note 1:
These parameters are characterized but not tested.
Data in âTypâ column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
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 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 âminâ values with an external clock applied to CLKIN pin. When an
external clock input is used, the âmaxâ cycle time limit is âDCâ (no clock) for all devices.
