AT90PWM2/3/2B/3B

Note:

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) under steady state

conditions (non-transient), the following must be observed:

SO32, SO24 and TQFN Package:

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

2] The sum of all IOL, for ports B6 - B7, C0 - C1, D0 - D3, E0 should not exceed 100 mA.

3] The sum of all IOL, for ports B0 - B1, C2 - C3, D4, E1 - E2 should not exceed 100 mA.

4] The sum of all IOL, for ports B3 - B5, C6 - C7 should not exceed 100 mA.

5] The sum of all IOL, for ports B2, C4 - C5, D5 - D7 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) under steady state

conditions (non-transient), the following must be observed:

SO32, SO24 and TQFN Package:

1] The sum of all IOH, for all ports, should not exceed 400 mA.

2] The sum of all IOH, for ports B6 - B7, C0 - C1, D0 - D3, E0 should not exceed 150 mA.

3] The sum of all IOH, for ports B0 - B1, C2 - C3, D4, E1 - E2 should not exceed 150 mA.

4] The sum of all IOH, for ports B3 - B5, C6 - C7 should not exceed 150 mA.

5] The sum of all IOH, for ports B2, C4 - C5, D5 - D7 should not exceed 150 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.
