Notes:

1. “Typ.”, typical values at 25°C. Maximum values are characterized values and not test limits in production.

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

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

4. Although each I/O port can sink more than the test conditions (10mA at V

CC= 5V, 5mA at VCC = 3V) under steady state con-

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

The sum of all IOL, for all ports, should not exceed 120mA.

If I

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

than the listed test condition.

5. Although each I/O port can source more than the test conditions (10mA at VCC = 5V, 5mA at VCC = 3V) under steady state

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

The sum of all IOH, for all ports, should not exceed 120mA.

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.

6. Values using methods described in “Minimizing Power Consumption” on page 49. Power Reduction is enabled

(PRR = 0xFF) and there is no I/O drive.

7. BOD disabled.
