Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.

2: Instruction cycle period (TCY) equals two 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/CLKI pin. When an external clock input is used, the

“max.” cycle time limit is “DC” (no clock) for all devices.

3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.

4: Data for this parameter is Preliminary. This parameter is characterized, but not tested in manufacturing.
