Notes: 1. VVDD corresponds to either VVDDIN or VVDDIO, depending on the supply for the pin. Refer to Section 3.2 on page 8 for details. 2. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-
cess technology. These values are not covered by test limits in production.
3. This applies to all normal drive pads except PB13, PB17 and PB18.
4. This applies to PB13, PB17 and PB18 pads only.
5. This applies to all normal drive pad except PA00, PA01, PA02, PA03, PA04, PA05, PA06, PA07, PA08, PA09, PA10, PA11,
PA12, PA13, PA18, PA19, PA27, PA30, PA31, PB13, PB16 and RESET_N.
