I/O output DC characteristics

The following tables provide DC characteristics for bidirectional pads:



Table 17 provides weak pull figures. Both pull-up and pull-down resistances are

supported.



Table 18 provides output driver characteristics for I/O pads when in SLOW

configuration.



Table 19 provides output driver characteristics for I/O pads when in MEDIUM

configuration.



Table 20 provides output driver characteristics for I/O pads when in FAST

configuration.

VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.

The configuration PAD3V5 = 1 when VDD = 5 V is only a transient configuration during power-up. All pads but RESET and

Nexus output (MDOx, EVTO, MCKO) are configured in input or in high impedance state.
