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.

4. Maximum values are characterized values and not test limits in production.

28.3

Speed Grades

Maximum frequency is dependent on V

CC. 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.

Figure 28-1. Maximum Frequency vs. V

A = -40°C to 85°C, VCC = 1.8V to 5.5V (unless otherwise noted)
