Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
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 OSCI/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 OSCO pin. CLKO is low for
the Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY).
