29.2.8 ATmega328P DC Characteristics
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.
29.3 Speed Grades
Maximum frequency is dependent on V
CC.
As shown in Figure 29-1, the Maximum Frequency vs. V
CC
curve is
linear between 1.8V < V
CC
< 2.7V and between 2.7V < V
CC
< 4.5V.
