1. Values with Minimizing Power Consumption enabled (0xFF).
2. Typical values at 25°C. Maximum values are test limits in production.
3. The current consumption values include input leakage current.
33.3 Speed Grades
Maximum frequency is dependent on V
CC.
As shown in the figure Maximum Frequency vs. V

, where
the curve is linear between 1.8V < V
CC
< 2.7V and between 2.7V < V
CC
< 4.5V.
