All I/Os are CMOS and TTL compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters. The
coverage of these requirements for FT I/Os is shown in
Figure 39.

1. Guaranteed by design.
2. Tested in production.
3. With a minimum of 200 mV.
4. Leakage could be higher than the maximum value, if negative current is injected on adjacent pins, Refer to Table 65: I/O
current injection susceptibility
5. To sustain a voltage higher than VDD +0.3 V, the internal pull-up/pull-down resistors must be disabled. Leakage could be
higher than the maximum value, if negative current is injected on adjacent pins.Refer to Table 65: I/O current injection
susceptibility
6. Pull-up resistors are designed with a true resistance in series with a switchable PMOS. This PMOS contribution to the
series resistance is minimum (~10% order).
7. Pull-down resistors are designed with a true resistance in series with a switchable NMOS. This NMOS contribution to the
series resistance is minimum (~10% order).
8. Hysteresis voltage between Schmitt trigger switching levels. Guaranteed by characterization results.
