Notes: 1. All DC Characteristics contained in this data sheet are based on simulation and characterization of other AVR microcontrollers manufactured in the same process technology. These values are preliminary values representing design targets, and will be updated after characterization of actual silicon.

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 (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

1] The sum of all IOL, for all ports, should not exceed 60 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.

5.Although each I/O port can source more than the test conditions (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

1] The sum of all IOH, for all ports, should not exceed 60 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.

Maximum Speed vs. VCC Maximum frequency is dependent on VCC. As shown in Figure 82 and Figure 83, the Maximum Frequency vs. VCC curve is linear between 1.8V < VCC < 2.7V and between 2.7V < VCC < 4.5V.
