11055E–ATARM–10-Mar-2014

Criteria used to define the maximum frequency of the I/Os:



Output duty cycle (40%–60%)



Minimum output swing: 100 mV to V

DDIO

 - 100 mV



Addition of rising and falling time inferior to 75% of the period

Notes: 1. 3.3V domain: V

DDIOP 

from 3.0V to 3.6V, maximum external capacitor = 20 pF

2. 1.8V domain: V

DDIOP 

from 1.65V to 1.95V, maximum external capacitor = 20 pF

Note:

1. If cable is connected add 200 µA (Typical) due to Pull-up/Pull-down current consumption.

Note:

1. Including 1mA due to Pull-up/Pull-down current consumption.
