Notes: 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.
4. Maximum values are characterized values and not test limits in production.
28.3 Speed Grades
Maximum frequency is dependent on VCC. As shown in Figure 28-1, the Maximum Frequency vs.
CC curve is linear between 1.8V < VCC < 2.7V and between 2.7V < VCC < 4.5V.
