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.”

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