AT90USB64/128

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 (20mA at VCC = 5V, 10mA at VCC = 3V) under steady state

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

AT90USB64/128:

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

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

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

4.)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 (20mA at VCC = 5V, 10mA at VCC = 3V) under steady

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

AT90USB64/128:

1)The sum of all IOH, for ports A0-A7, G2, C4-C7 should not exceed 100 mA.

2)The sum of all IOH, for ports C0-C3, G0-G1, D0-D7 should not exceed 100 mA.

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

4)The sum of all IOH, for ports F0-F7 should not exceed 100 mA.

5. All DC Characteristics contained in this datasheet are based on simulation and characterization of other AVR microcontrol-

lers manufactured in the same process technology. These values are preliminary values representing design targets, and

will be updated after characterization of actual silicon

6. Values with “Power Reduction Register 1 - PRR1” disabled (0x00).
