Electrical characteristics
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 23 and
Table 54, respectively.
Table 54.
Unless otherwise specified, the parameters given are derived from tests performed under
ambient temperature and VDD supply voltage conditions summarized in Table 22.

1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the RM0316 reference manual for a description of
GPIO Port configuration register.
2. The maximum frequency is defined in Figure 23.
3. Guaranteed by design, not tested in production.
4. The I/O speed configuration is bypassed in FM+ I/O mode. Refer to the STM32F30xB/C reference manual RM0316 for a
description of FM+ I/O mode configuration.
