ATmega325P/3250P

Notes:

1. “Max” means the highest value where the pin is guaranteed to be read as low

2. “Min” means the lowest value where the pin is guaranteed to be read as high

3. Although each I/O port can sink more than the test conditions (20 mA at V

CC = 5V, 10 mA at VCC = 3V for Port B and 10 mA

at V

CC = 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] The sum of all IOL, for all ports, should not exceed 400 mA.

2] The sum of all IOL, for ports A0 - A7, C4 - C7, G2 should not exceed 100 mA.

3] The sum of all IOL, for ports B0 - B7, E0 - E7, G3 - G5 should not exceed 100 mA.

4] The sum of all IOL, for ports D0 - D7, C0 - C3, G0 - G1 should not exceed 100 mA.

5] The sum of all IOL, for ports F0 - F7, should not exceed 100 mA.

If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater

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 10mA

at V

CC = 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] The sum of all IOL, for all ports, should not exceed 400 mA.

2] The sum of all IOL, for ports A0 - A7, C4 - C7, G2 should not exceed 100 mA.

3] The sum of all IOL, for ports B0 - B7, E0 - E7, G3 - G5 should not exceed 100 mA.

4] The sum of all IOL, for ports D0 - D7, C0 - C3, G0 - G1 should not exceed 100 mA.

5] The sum of all IOL, for ports F0 - F7, should not exceed 100 mA.

If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current

greater than the listed test condition.
