SR D

Sum of all the static

I/O current within a

supply segment

VDD = 5.0 V ± 10%, PAD3V5V = 0

—

VDD = 3.3 V ± 10%, PAD3V5V = 1

—

VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = –40 to 125 °C, unless otherwise specified

Stated maximum values represent peak consumption that lasts only a few ns during I/O transition.

Start-up time(1),(2)

The start-up time is dependent upon crystal characteristics, board leakage, etc., high ESR and excessive

capacitive loads can cause long start-up time.

Value captured when amplitude reaches 90% of EXTAL
