I/O Characteristics
The voltage and current characteristics of the various IO pads of the VZM20Q
versus IO bank supply voltage are illustrated in the tables below.
versus IO bank supply voltage are illustrated in the tables below.
Caution:
Note that the V
oh
values in the tables below do not apply to
GPIOs configured in open drain mode. GPIOs can be individually
configured in open drain mode. When in open drain mode they
either drive the line to V
ol
, or leave it floating, to be pulled up by
an external pullup resistance. The PCB designer must ensure that
the voltage on these pads never exceeds V

of the IO group to
which they belong.
Refer to VZM20Q Pin List to know the type of IO pad used on every
termination.

• The Minimum values for I
ol
and I
oh
should not be exceeded to guarantee
that the logical level are not spoiled for each pad type.
The Nominal values for I
ol
and I
oh
represent the nominal values for the pad
type. They are provided for information only.
