7.7 Electrical Characteristics

Note

The interfaces or signals described in Section 7.7.1 through Section 7.7.10 correspond to the

interfaces or signals available in multiplexing mode 0 (Primary Function).

All interfaces or signals multiplexed on the balls described in these tables have the same DC electrical

characteristics, unless multiplexing involves a PHY and GPIO combination, in which case different DC

electrical characteristics are specified for the different multiplexing modes (Functions).

V/s

(1)

VDD stands for corresponding power supply. For more information on the power supply name and the corresponding ball(s), see

POWER column of the Pin Attributes table.

(2)

This value also defines the Absolute Maximum Ratings value the IO.

(3)

The IOL parameter defines the minimum Low Level Output Current for which the device is able to maintain the specified VOL value.

The value defined by this parameter should be considered the maximum current available to a system implementation which needs to

maintain the specified VOL value for attached components.

(4)

f = toggle frequency of the input signal in Hz.

(5)

This MIN parameter only applies to input signal functions which are not defined in their respective Timing and Switching

Characteristics sections. Select the MIN parameter which results in the largest value.

(6)

I2C Hs-mode is not supported when operating the IO in 3.3 V mode.
