Note:
  1. “Max” means the highest value where the pin is ensured to be read as low.
  2. “Min” means the lowest value where the pin is ensured to be read as high.
  3. Although each I/O port can sink more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC= 3V for Port B and 10 mA at VCC = 5V, 5 mA at VCC = 3V for all other ports) under steady-state conditions (non-transient), the following must be observed.
    • TQFP and QFN/MLF Package:
      1. For all ports, the sum of all IOL may not exceed 400 mA.
      2. For ports A0 - A7, C4 - C7, and G2, the sum of all IOL may not exceed 100 mA.
      3. For ports B0 - B7, E0 - E7, and G3 - G5, the sum of all IOL may not exceed 100 mA.
      4. For ports D0 - D7, C0 - C3, and G0 - G1, the sum of all IOL may not exceed 100 mA.
      5. For ports F0 - F7, the sum of all IOL may not exceed 100 mA.

      If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not ensured to sink current higher than the listed test condition.

  4. Although each I/O port can source more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V for Port B and 10 mA at VCC = 5V, 5 mA at VCC = 3V for all other ports) under steady-state conditions (non-transient), observe the following:
    • TQFP and QFN/MLF Package:
      1. For all ports, the sum of all IOH may not exceed 400 mA.
      2. For ports A0 - A7, C4 - C7, and G2, the sum of all IOH may not exceed 100 mA.
      3. For ports B0 - B7, E0 - E7, and G3 - G5, the sum of all IOH may not exceed 100 mA.
      4. For ports D0 - D7, C0 - C3, and G0 - G1, the sum of all IOH may not exceed 100 mA.
      5. For ports F0 - F7, the sum of all IOH may not exceed 100 mA.

      If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not ensured to source current higher than the listed test condition

  5. Largest value for ATmega325PA and ATmega3250PA.
  6. These values are based on characterization. The maximum limit in production can, therefore, not be assured.
