45.10 I/Os
Criteria used to define the maximum frequency of the I/Os:
z Output duty cycle (40%-60%)
z Minimum output swing: 100 mV to VDDIO - 100 mV
z Addition of rising and falling time inferior to 75% of the period
Notes: 1. 3.3V domain: V
VDDIOP
from 3.0V to 3.6V, maximum external capacitor = 40 pF
2. 1.8V domain: V
VDDIOP
from 1.65V to 1.95V, maximum external capacitor = 20 pF
45.11 USB HS Characteristics
45.11.1 Electrical Characteristics
45.11.2 Static Power Consumption
Note: 1. If cable is connected add 200 µA (Typical) due to Pull-up/Pull-down current consumption.
