I/O port characteristics

General input/output characteristics

Unless otherwise specified, the parameters given in Table 49 are derived from tests

performed under the conditions summarized in Table 13: General operating conditions.

All I/Os are CMOS and TTL compliant except for BOOT0 and BOOT1.

1. TBD stands for “to be defined”.

2. Data based on design simulation only. Not tested in production.

3. Tested in production.

4. To sustain a voltage higher than VDD +0.3 V, the internal pull-up/pull-down resistors must be disabled.

5. With a minimum of 200 mV.

6. Leakage could be higher than the maximum value, if negative current is injected on adjacent pins.

7. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This

MOS/NMOS contribution to the series resistance is minimum (~10% order)
