3.6 I/O Characteristics
The voltage and current characteristics of the various IO pads of the SP150Q
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 pull-up resistance. The PCB designer must ensure that
the voltage on these pads never exceeds V
ih
of the IO group to
which they belong.
Table 3-4 details the various pad types as listed in SP150Q signals list.
Refer to SP150Q 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.
