I/O output DC characteristics

The following tables provide DC characteristics for bidirectional pads:

●

Table 15 provides weak pull figures. Both pull-up and pull-down resistances are

supported.

●

Table 16 provides output driver characteristics for I/O pads when in SLOW

configuration.

●

Table 17 provides output driver characteristics for I/O pads when in MEDIUM

configuration.

●

Table 18 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.

VDD as mentioned in the table is VDD_HV_A/VDD_HV_B. All values need to be confirmed during device validation.

Analog filters are available on all wakeup lines.

The width of input pulse in between 40 ns to 1000 ns is indeterminate. It may pass the noise or may not depending on

silicon sample to sample variation.
