†

Data in “Typ” column is at VIN =12V (VDD = 5V), +25°C unless otherwise stated. These parameters are for

design guidance only and are not tested.

Note 1:

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.
