Note: 1. V
VDD
corresponds to either V
VDDIO1
, V
VDDIO2
, V
VDDIO3
, or V
VDDANA
, depending on the supply for the pin. Refer to Section 3-1
on page 11 for details.
2. drive x1 capability pins are: PB00, PB01, PB02, PB03, PB30, PB31, PC02, PC03, PC04, PC05, PC06, PC07 - drive x2 /x4
capability pins are: PB06, PB21, PB26, PD02, PD06, PD13 - drive x1/x2 capability pins are the remaining PA, PB, PC, PD
pins. The drive strength is programmable through ODCR0, ODCR0S, ODCR0C, ODCR0T registers of GPIO.
3. 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.
