4.7.4 Pad Properties
The output pad drivers of the XC2734X can operate in several user-selectable modes.
Strong driver mode allows controlling external components requiring higher currents
such as power bridges or LEDs. Reducing the driving power of an output pad reduces
electromagnetic emissions (EME). In strong driver mode, selecting a slower edge
reduces EME.
The dynamic behavior, i.e. the rise time and fall time, depends on the applied external
capacitance that must be charged and discharged. Timing values are given for a
capacitance of 20 pF, unless otherwise noted.
In general, the performance of a pad driver depends on the available supply voltage
V_DDP. Therefore the following tables list the pad parameters for the upper voltage range
and the lower voltage range, respectively.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.
Table 27 is valid under the following conditions: V_DDP≤ 5.5 V; V_DDPtyp. 5 V; V_DDP≥ 4.5 V
