(Note 4)

Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are characterized but are not

tested.

2: Instruction cycle period (TCY) equals 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.

3: PLL input requirements: 4 MHZ  FPLLIN  5 MHZ (use PLL prescaler to reduce FOSC). This parameter is

characterized, but tested at 10 MHz only at manufacturing.

4: This parameter is characterized, but not tested in manufacturing.
