I/O port characteristics

General input/output characteristics

Unless otherwise specified, the parameters given in Table 50: I/O static characteristics are

derived from tests performed under the conditions summarized in Table 12: General

operating conditions. All I/Os are CMOS and TTL compliant (except for BOOT0).

Note:

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

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

website www.st.com.
