Note:

It is recommended to add a Schottky diode (pin to ground) to analog pins, which may

potentially inject negative currents.

I/O port characteristics

General input/output characteristics

Unless otherwise specified, the parameters given in Table 57: I/O static characteristics are

derived from tests performed under the conditions summarized in Table 17. All I/Os are

CMOS and TTL compliant.

Note:

For information on GPIO configuration, refer to the application note AN4899 “STM32 GPIO

configuration for hardware settings and low-power consumption” available from

www.st.com.
